2011-02-03USB: fix race between root-hub resume and wakeup requestsAlan Stern
The USB core keeps track of pending resume requests for root hubs, in order to resolve races between wakeup requests and suspends. However the code that does this is subject to another race (between wakeup requests and resumes) because the WAKEUP_PENDING flag is cleared before the resume occurs, leaving a window in which another wakeup request might arrive. This patch (as1447) fixes the problem by clearing the WAKEUP_PENDING flag after the resume instead of before it. This fixes Bugzilla #24952.

If anyone comes across a high-speed hub that (by mistake or by design) claims to have no Transaction Translators, plugging a full- or low-speed device into it will cause the USB stack to crash. This patch (as1446) prevents the problem by ignoring such devices, since the kernel has no way to communicate with them.

In drivers/usb/host/sl811-hcd.c::sl811h_urb_enqueue(), memory is allocated with kzalloc() and assigned to 'ep'. If we leave via the 'fail' label due to 'if (ep->maxpacket > H_MAXPACKET)', then 'ep' will go out of scope without having been assigned to anything, so we'll leak the memory we allocated. This patch fixes the leak by simply calling kfree(ep); before jumping to the 'fail' label. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2011-02-01usb: musb: introduce api for dma code to check compatibility with usb requestMian Yousaf Kaukab
Gadget MUSB driver handles dma mappings in musb_gadget_queue(). Where as it is possible for dma code to reject the usb request later at ->channel_program() called from txstate()/rxstate() For example ->channel_program in tusb6010_omap.c: static int tusb_omap_dma_program(struct dma_channel *channel, u16 packet_sz, u8 rndis_mode, dma_addr_t dma_addr, u32 len) { ... if (unlikely(dma_addr & 0x1) || (len < 32) || (len > packet_sz)) return false; ... if (dma_addr & 0x2) return false; ... } In this case, usb request will be handled in PIO mode which renders dma mapping operations unnecessary. This patch adds an api to allow dma code to indicate incompatibility with usb request. Gadget musb driver call this api, if available, before dma mappings to avoid any unnecessary mapping operations.

2011-02-01usb: musb: maintain three states for buffer mappings instead of twoMian Yousaf Kaukab
If dma buffers are mapped by a higher layer, with a boolean musb_request.mapped it is still possible to call dma_sync_single_for_device() from musb_g_giveback(), even if txstate()/rxstate() has called unmap_dma_buffer() before falling back to pio mode. Moreover, check for musb_ep->dma is moved within map_dma_buffer() so where applicable checks for it are removed. And where possible, checks for is_dma_capable() are merged with buffer map state check.

We know that blackfin doesn't support double buffering feature as of today. So we add a flag set by musb_platform_init() to forcefully disable that feature. Such flag is created and marked as deprecated to force us to find a solution for the missing double buffering support on blackfin. Signed-off-by: Felipe Balbi <balbi@ti.com>

Alan's commit 335f8514f200e63d689113d29cb7253a5c282967 introduced .carrier_raised function in several drivers. That also means tty_port_block_til_ready can now suspend the process trying to open the serial port when Carrier Detect is low and put it into tty_port.open_wait queue. We need to wake up the process when Carrier Detect goes high and trigger TTY hangup when CD goes low. Some of the devices do not report modem status line changes, or at least we don't understand the status message, so for those we remove .carrier_raised again.

2011-01-22USB: ehci-fsl: Fix 'have_sysif_regs' detectionPeter Tyser
Previously a check was done on an ID register at the base of a CPU's internal USB registers to determine if system interface regsiters were present. The check looked for an ID register that had the format ID[0:5] == ~ID[8:13] as described in the MPC5121 User's Manual to determine if a MPC5121 or MPC83xx/85xx was being used. There are two issues with this method: - The ID register is not defined on the MPC83xx/85xx CPUs, so its unclear what is being checked on them. - Newer CPUs such as the P4080 also don't document the ID register, but do share the same format as the MPC5121. Thus the previous code did not set 'have_sysif_regs' properly which results in the P4080 not properly initializing its USB ports. Using the device tree 'compatible' node is a cleaner way to determine if 'have_sysif_regs' should be set and resolves the USB initialization issue seen on the P4080. Tested on a P4080-based system and compile tested on mpc512x_defconfig with Freescale EHCI driver enabled.

This patch (as1442) fixes a bug in g_printer: Module parameters should not be marked "__initdata" if they are accessible in sysfs (i.e., if the mode value in the module_param() macro is nonzero). Otherwise attempts to access the parameters will cause addressing violations. Character-string module parameters must not be marked "__initdata" if the module can be unloaded, because the kernel needs to access the parameter variable at unload time in order to free the dynamically-allocated string.
