Subject: [PATCH 2/3] soc: qcom: rpmh-rsc: Loop over less bits in irq handler
Date: Thu, 23 Apr 2020 21:54:13 -0700 [thread overview]
Message-ID: <20200424045414.133381-3-swboyd@chromium.org> (raw)
In-Reply-To: <20200424045414.133381-1-swboyd@chromium.org>
readl returns a u32, and BITS_PER_LONG is different on 32-bit vs. 64-bit
architectures. Let's make the type we stash the readl into a u32 and
then loop over the bits set in that type instead of potentially looping
over more bits than we will ever need to.
