Revert "Merge remote-tracking branch 'arm-soc/for-next' into linaro-3.0"
This reverts commit c7e0c8535d73f8c5bf760926a2bd71c9840cf2ef, reversing changes made to dfee09c8acf18e84fe197bb5d821d1e4e02d020f. John Stultz reports that Panda doesn't boot anymore and 'git bisect' indicated the merge commit itself as the culprit. The resulting kernel log is: [ 1.734802] OMAP DSS rev 4.0 [ 1.740417] omap_hwmod: dss_core: _wait_target_disable failed [ 1.746429] omap_device: omapdss_dss.-1: new worst case deactivate latency 01 [ 1.755035] omapdss DISPC error: can't get dss_clk [ 1.760101] omapdss_dispc: probe of omapdss_dispc failed with error -2 [ 1.767333] omapdss HDMI error: can't get hdmi_clk [ 1.772399] omapdss_hdmi: probe of omapdss_hdmi failed with error -2 [ 1.780273] ------------[ cut here ]------------ [ 1.785125] WARNING: at drivers/video/omap2/dss/dispc.c:553dispc_runtime_ge) [ 1.793640] Modules linked in: [ 1.796905] ---[ end trace 6fcb132ac310d004 ]--- [ 1.801757] Unable to handle kernel NULL pointer dereference at virtualaddr0 [...] Revert it so a later version of the arm-soc merge result can be used instead.
