[PATCH v3 2/3] soc: qcom: rpmh-rsc: Loop over fewer bits in irq handler

From: Stephen Boyd
Date: Wed May 20 2020 - 21:21:34 EST


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.
