Fix a NULL pointer exception when main exynos drm driver was probed successfully but no components were added (e.g. by incomplete DTS). In such case the exynos_drm_load() is never called and drvdata is NULL. The NULL pointer exception may theoretically also happen as a effect of race between adding components and main driver: if suspend of the driver happens before adding components.

由 Thierry Reding 提交于
To implement hotplug detection in a race-free manner, drivers must call drm_kms_helper_poll_init() before hotplug events can be triggered. Such events can be triggered right after any of the encoders or connectors are initialized. At the same time, if the drm_fb_helper_hotplug_event() helper is used by a driver, then the poll helper requires some parts of the FB helper to be initialized to prevent a crash. At the same time, drm_fb_helper_init() requires information that is not necessarily available at such an early stage (number of CRTCs and connectors), so it cannot be used yet. Add a new helper, drm_fb_helper_prepare(), that initializes the bare minimum needed to allow drm_kms_helper_poll_init() to execute and any subsequent hotplug events to be processed properly.

If there is no panel node in DT and instead display timings are provided directly in FIMD node, there is no panel object created and ctx->panel becomes NULL. However during Exynos DRM initialization drm_helper_hpd_irq_event() is called, which in turns calls exynos_dpi_detect(), which dereferences ctx->panel without a check, causing a NULL pointer derefrence. This patch fixes the issue by adding necessary NULL pointer check.

Drivers really have no business touching these. Noticed because exynose _did_ touch the vblank off delay, which could potentially affect other drivers. drm_debug is an exception since it's used in macros and inline functions. Note that this reduces the timeout on exynos from 50s to 5s. Apparently this was done to paper over a vblank get/put race in exynos, but really should be fixed properly somewhere else. Spotted by David. v2: Drop bonghits changes. Note to self: Don't submit patches before first coffee.

This patch makes sure that exynos drm framework handles deferred probe case correctly. Sub drivers could be probed before resources, clock, regulator, phy or panel, are ready for them so we should make sure that exynos drm core waits until all resources are ready and sub drivers are probed correctly. Chagelog v2: - Make sure that exynos drm core tries to bind sub drivers only in case that they have a pair: crtc and encoder/connector components should be a pair. - Remove unnecessary patch: drm/exynos: mipi-dsi: consider panel driver-deferred probe - Return error type correctly.
