This fixes a lockup at device probing which happens on some solo6010 hardware samples. This is a regression introduced by commit e1ceb25a ("[media] SOLO6x10: remove unneeded register locking and barriers") The observed lockup happens in solo_set_motion_threshold() called from solo_motion_config(). This extra "flushing" is not fundamentally needed for every write, but apparently the code in driver assumes such behaviour at last in some places. Actual fix was proposed by Hans Verkuil. Fixes: e1ceb25a ("[media] SOLO6x10: remove unneeded register locking and barriers") Cc: stable@vger.kernel.org # 4.3 and up Signed-off-by:

If the driver is built as a module, autoload won't work because the module alias information is not filled. So user-space can't match the registered device with the corresponding module. Export the module alias information using the MODULE_DEVICE_TABLE() macro.

The devm_ioremap_resource() returns error pointers, never NULL. The platform_get_resource() returns NULL on error, never error pointers. The error code needs to be set, as well. The current code returns PTR_ERR(NULL) which is success. Fixes: 57b2c062 ("[media] st-hva: multi-format video encoder V4L2 driver") Signed-off-by:

A bugfix removed the two callers of s5p_cec_runtime_suspend and s5p_cec_runtime_resume, leading to the return of a harmless warning that I had previously fixed in commit aee89370 ("[media] s5p_cec: mark suspend/resume as __maybe_unused"): staging/media/s5p-cec/s5p_cec.c:234:12: error: ‘s5p_cec_runtime_suspend’ defined but not used [-Werror=unused-function] staging/media/s5p-cec/s5p_cec.c:242:12: error: ‘s5p_cec_runtime_resume’ defined but not used [-Werror=unused-function] This adds the __maybe_unused annotations to the function that were not removed and that are now unused when CONFIG_PM is disabled.
