Subject: [PATCH] drm/lima: Reduce the amount of logs on deferred probe
commit 34e88f9e2fff2d46a206e4d94c9e8fdf45b85d9a upstream.
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.
Fixes: a1d2a6339961 ("drm/lima: driver for ARM Mali4xx GPUs")
