Subject: lib/percpu_counter: add missing __percpu qualifier to a cast
Date: Wed, 14 Aug 2024 08:44:13 +0200
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.
