drm/tilcdc: fix wrong error handling

2016-09-23T12:12:57Z

When 'component_bind_all' fails it should not try to unbind components in the error handling. This will produce a null pointer kernel panic when no component exist. This patch changes the order of the error handling. Now, it will only unbind components if the are bound. Otherwise, the module will jump to an error label below.

drm/tilcdc: Return directly after a failed kfree_table_init() in tilcdc_convert_slave_node()

drm/tilcdc: Fix non static symbol warning

2016-09-22T20:50:09Z

Fixes the following sparse warning: drivers/gpu/drm/tilcdc/tilcdc_drv.c:64:5: warning: symbol 'tilcdc_atomic_check' was not declared. Should it be static? Signed-off-by: Wei Yongjun Signed-off-by: Jyri Sarha

drm/tilcdc: mark symbols static where possible

2016-09-22T20:50:09Z

We get 3 warnings when building kernel with W=1: drivers/gpu/drm/tilcdc/tilcdc_slave_compat.c:142:29: warning: no previous prototype for 'tilcdc_get_overlay' [-Wmissing-prototypes] drivers/gpu/drm/tilcdc/tilcdc_slave_compat.c:198:13: warning: no previous prototype for 'tilcdc_convert_slave_node' [-Wmissing-prototypes] drivers/gpu/drm/tilcdc/tilcdc_slave_compat.c:264:12: warning: no previous prototype for 'tilcdc_slave_compat_init' [-Wmissing-prototypes] In fact, these functions are only used in the file in which they are declared and don't need a declaration, but can be made static. So this patch marks these functions with 'static'. Signed-off-by: Baoyou Xie Signed-off-by: Jyri Sarha

drm/tilcdc: add missing header dependencies

2016-09-22T20:50:08Z

We get 4 warnings when building kernel with W=1: drivers/gpu/drm/tilcdc/tilcdc_tfp410.c:393:12: warning: no previous prototype for 'tilcdc_tfp410_init' [-Wmissing-prototypes] drivers/gpu/drm/tilcdc/tilcdc_tfp410.c:398:13: warning: no previous prototype for 'tilcdc_tfp410_fini' [-Wmissing-prototypes] drivers/gpu/drm/tilcdc/tilcdc_panel.c:443:12: warning: no previous prototype for 'tilcdc_panel_init' [-Wmissing-prototypes] drivers/gpu/drm/tilcdc/tilcdc_panel.c:448:13: warning: no previous prototype for 'tilcdc_panel_fini' [-Wmissing-prototypes] In fact, these functions are declared in drivers/gpu/drm/tilcdc/tilcdc_tfp410.h, drivers/gpu/drm/tilcdc/tilcdc_panel.h, so this patch adds missing header dependencies.

drm/tilcdc: WARN if CRTC is touched without CRTC lock

2016-09-07T12:54:43Z

WARN if CRTC is touched without CRTC lock. The crtc functions should not be called simultaneously from multiple threads. Having the DRM CRTC lock should take care of that. Signed-off-by: Jyri Sarha Reviewed-by: Tomi Valkeinen

drm/tilcdc: Take CRTC lock when calling tilcdc_crtc_disable()

2016-09-07T12:54:42Z

Take CRTC lock when calling tilcdc_crtc_disable() in tilcdc_crtc_destroy(). In theory there could still be some operation ongoing, which should finish before destroying the CRTC. However, the main reason for adding this is to be able to add WARNing in tilcdc_crtc_disable() if CRTC is not locked. Signed-off-by: Jyri Sarha Reviewed-by: Tomi Valkeinen

drm/tilcdc: Remove unnecessary tilcdc_crtc_disable() from tilcdc_unload()

2016-09-07T12:54:42Z

Remove unnecessary tilcdc_crtc_disable() from tilcdc_unload(). The tilcdc_crtc_disable() called via tilcdc_crtc_destroy() by drm_mode_config_cleanup() couple of lines later. The early call to tilcdc_crtc_disable() was a wrong fix (that worked) for calling drm_flip_work_cleanup() before flushing the flip-work queue. Signed-off-by: Jyri Sarha Reviewed-by: Tomi Valkeinen
