Date: Wed, 20 May 2020 18:21:18 -0700 From: Stephen Boyd <swboyd@...omium.org> To: unlisted-recipients:; (no To-header on input) Cc: linux-kernel@...r.kernel.org, Maulik Shah <mkshah@...eaurora.org>, Douglas Anderson <dianders@...omium.org>, Bjorn Andersson <bjorn.andersson@...aro.org> Subject: [PATCH v3 2/3] 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.
