Subject: [PATCHv3/RESEND 2/3] soc: qcom: rpmh-rsc: Loop over fewer bits in irq handler
Date: Wed, 20 May 2020 23:04:24 -0700	[thread overview]
Message-ID: <20200521060425.24285-3-swboyd@chromium.org> (raw)
In-Reply-To: <20200521060425.24285-1-swboyd@chromium.org>

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.
