If we use the gem fb helper as the prepare_fb hook, plus the drm_prime.c import helpers now automatically setting obj->resv, we can use the shared helpers to wait for fences instead of rolling our own. Note that this relies on mtk setting drm_fb->obj, which is already done in mtk_drm_framebuffer_init(). Aside: Probably can use the default commit_tail with this again, but I didn't check for that.

The commit 3aeeb13d ("drm/modes: Support modes names on the command line") added name support to the DRM modes, and added that name to the debug message. However, that code tests for whether or not the name variable is NULL and only prints it if it's not. Except that that variable is an array, so it will never be NULL. The original intent was to print it only when the name has been specified. Just printing the array directly will achieve the same thing since the drm_cmdline_mode structure that holds it is itself contained in drm_connector, that is allocated with its whole content zero'd. That means that if the name is not declared, the array will be all zeros, which will not print anything. Cc: Nick Desaulniers <ndesaulniers@google.com> Reported-by:

There is no point to print deferred probe messages as errors. Adjust the printks for error paths of obtaining clocks and reset controller. This removes the error message of lima_clk_init() call in favor or specific failure messages inside. Signed-off-by:

There is no point to print deferred probe (and its failures to get resources) as an error. For example getting a regulator causes three unneeded error messages: lima 13000000.gpu: failed to get regulator: -517 lima 13000000.gpu: regulator init fail -517 lima 13000000.gpu: Fatal error during GPU init Also do not print clock rates before the initialization finishes because they will be duplicated after deferral. Each probe step already prints error so remove the final error message "Fatal error during GPU init". In case of multiple probe tries this would pollute the dmesg.

It looks like this was done purely to get a consistent place to look up the reservation object pointer. With the drm_prime.c helper code now also setting gem_object->resv for imported objects we can just use that pointer directly, instead of first ensuring a dma-buf exists. v2: Note that I screwed up the patch ordering, hence why this needed a Fixes: tag - CI spotted the broken intermediate state.
