Subject: [PATCH 1/2] perf: arm_dsu_pmu: convert to bitmap_from_arr32

From: Arnd Bergmann <arnd@...db.de>

The bitmap_from_u32array() interface got replaced in a global
change, but the arm_dsu_pmu driver adds another instance,
resulting in a build failure:

drivers/perf/arm_dsu_pmu.c: In function 'dsu_pmu_probe_pmu':
drivers/perf/arm_dsu_pmu.c:661:2: error: implicit declaration of function 'bitmap_from_u32array'; did you mean 'bitmap_from_arr32'? [-Werror=implicit-function-declaration]

This changes the new instance accordingly.

Fixes: mmotm ("bitmap: replace bitmap_{from,to}_u32array")
Fixes: 7520fa99246d ("perf: ARM DynamIQ Shared Unit PMU support")
