[v2] staging: media: meson: vdec: propagate devm_clk_get() errors

[PATCH v2] staging: media: meson: vdec: propagate devm_clk_get() errors

Posted by Alfie Varghese 1 week, 4 days ago

vdec_probe() hardcodes -EPROBE_DEFER for all devm_clk_get() failures.
This masks the actual error code returned by the clock framework, such
as -ENOENT when a clock is not registered or -ENOMEM on allocation
failure.

Return PTR_ERR() instead to propagate the real error to the caller.

Fixes: 4f75e7dfa6dc ("media: meson: vdec: add driver")
