drm/exynos: fix error handling in exynos_drm_subdrv_open

2016-11-24T15:23:34Z

commit 55c4b906aa2aec3fa66310ec03c6842e34a04b2a upstream. gcc-6 warns about a pointless loop in exynos_drm_subdrv_open: drivers/gpu/drm/exynos/exynos_drm_core.c: In function 'exynos_drm_subdrv_open': drivers/gpu/drm/exynos/exynos_drm_core.c:104:199: error: self-comparison always evaluates to false [-Werror=tautological-compare] list_for_each_entry_reverse(subdrv, &subdrv->list, list) { Here, the list_for_each_entry_reverse immediately terminates because the subdrv pointer is compared to itself as the loop end condition. If we were to take the current subdrv pointer as the start of the list (as we would do if list_for_each_entry_reverse() was not a macro), we would iterate backwards over the &exynos_drm_subdrv_list anchor, which would be even worse. Instead, we need to use list_for_each_entry_continue_reverse() to go back over each subdrv that was successfully opened until the first entry.

drm/exynos: fix return value check in lowlevel_buffer_allocate()

2013-09-16T12:57:08Z

In case of error, the function drm_prime_pages_to_sg() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR(). Signed-off-by: Wei Yongjun Signed-off-by: Inki Dae

drm/exynos: Remove redundant OF dependency

2013-09-16T12:57:03Z

Now that DRM_EXYNOS depends on OF, we do not need individual drivers to depend on it. Signed-off-by: Sachin Kamat Signed-off-by: Inki Dae

drm/exynos: Fix build error with exynos_drm_connector.c

2013-09-05T04:43:46Z

exynos_drm_connector.c now uses videomode helper API. Hence select VIDEOMODE_HELPERS at DRM_EXYNOS level itself instead of at DRM_EXYNOS_FIMD to avoid the following compilation error when FIMD is not selected (introduced by commit cf796235a6 "drm/exynos: fimd: replace struct fb_videomode with videomode"): drivers/built-in.o: In function `exynos_drm_connector_get_modes': drivers/gpu/drm/exynos/exynos_drm_connector.c:86: undefined reference to `drm_display_mode_from_videomode' Signed-off-by: Sachin Kamat Signed-off-by: Inki Dae

drm/exynos: Remove non-DT support in exynos_drm_fimd

2013-09-05T04:43:46Z

Since commit 383ffda2fa ("ARM: EXYNOS: no more support non-DT for EXYNOS SoCs"), Exynos platform is DT only. Hence remove all the conditional macros and make the driver DT only. Signed-off-by: Sachin Kamat Signed-off-by: Inki Dae
