[PATCH] lib/percpu_counter: Add missing __percpu qualifier to a cast

From: Uros Bizjak
Date: Wed Aug 14 2024 - 02:44:51 EST


Add missing __percpu qualifier to a (void *) cast to fix

percpu_counter.c:212:36: warning: cast removes address space '__percpu' of expression
percpu_counter.c:212:33: warning: incorrect type in assignment (different address spaces)
percpu_counter.c:212:33: expected signed int [noderef] [usertype] __percpu *counters
percpu_counter.c:212:33: got void *

sparse warnings.

Found by GCC's named address space checks.

There were no changes in the resulting object file.
