[PATCH 17/18] staging: lustre: fix 'no effect' errors

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

 



From: Sebastien Buisson <sbuisson@xxxxxxx>

Fix 'no effect' issues found by Coverity version 6.5.1:

Unsigned compared against 0 (NO_EFFECT)
This greater-than-or-equal-to-zero comparison of an unsigned value
is always true.

Remove useless cast.
