Subject: [PATCH] drivers/input/ff-core.c needs From: Geert Uytterhoeven commit 656acd2bbc4ce7f224de499ee255698701396c48 Author: Dmitry Torokhov Date: Thu Jun 26 11:30:02 2008 -0400 Input: fix locking in force-feedback core The newly added event_lock spinlock in the input core disallows sleeping and therefore using mutexes in event handlers. Convert force-feedback core to rely on event_lock instead of mutex to protect slots allocated for fore-feedback effects. The original mutex is still used to serialize uploading and erasing of effects. causes the following regression on m68k: | linux/drivers/input/ff-core.c: In function 'input_ff_upload': | linux/drivers/input/ff-core.c:172: error: dereferencing pointer to incomplete type | linux/drivers/input/ff-core.c: In function 'erase_effect': | linux/drivers/input/ff-core.c:197: error: dereferencing pointer to incomplete type | linux/drivers/input/ff-core.c:204: error: dereferencing pointer to incomplete type | make[4]: *** [drivers/input/ff-core.o] Error 1 As the incomplete type is `struct task_struct', including fixes it.
