[PATCH 2/3] drm/etnaviv: Don't ignore errors on getting clocks

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There might be good reasons why the getting a clock failed. To treat the
clocks as optional we're specifically only interested in ignoring -ENOENT,
and devm_clk_get_optional() does just that.
