[PATCH linux-next] drm/i915/display: Delete redundant post_mask assignment

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

 



From: luo penghao <luo.penghao@xxxxxxxxxx>

This value will be overwritten by the following if statement, even
if the if is not executed, the value will not be used

The clang_analyzer complains as follows:

Value stored to 'port_mask' is never read
