[PATCH v3 5/7] memory: mtk-smi: Fix the return value for clk_bulk_prepare_enable
Posted by Yong Wu 2 years, 8 months ago
Function clk_bulk_prepare_enable() returns 0 for success or a negative
number for error. Fix this code style issue.

The message does not really make sense. If negative is returned, then
the check (ret < 0) was correct.

I guess you wanted to say that common code style is to check for any
non-zero return value, just like it's implementation in clk.h does.

I'll adjust the commit msg when applying.
