From: Stephen Boyd Date: Thu, 21 May 2020 06:04:24 +0000 (-0700) Subject: soc: qcom: rpmh-rsc: Loop over fewer bits in irq handler X-Git-Tag: v5.13-rc1~168^2~11^2~3 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a07766206baf6272226df577fce920e931706006;p=thirdparty%2Fkernel%2Flinux.git soc: qcom: rpmh-rsc: Loop over fewer bits in irq handler readl() returns a u32, and BITS_PER_LONG is different on 32-bit vs. 64-bit architectures. Let's loop over the possible bits set in that type instead of looping over more bits than we ever may need to.
