soc: rockchip: work around clang warning
clang emits a warning about a negative shift count for an
unused part of a conditional constant expression:
drivers/soc/rockchip/pm_domains.c:795:21: error: shift count is negative [-Werror,-Wshift-count-negative]
[RK3328_PD_VIO] = DOMAIN_RK3328(-1, 8, 8, false),
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/soc/rockchip/pm_domains.c:129:2: note: expanded from macro 'DOMAIN_RK3328'
DOMAIN_M(pwr, pwr, req, (req) + 10, req, wakeup)
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/soc/rockchip/pm_domains.c:105:33: note: expanded from macro 'DOMAIN_M'
.status_mask = (status >= 0) ? BIT(status) : 0, \
^~~~~~~~~~~
include/linux/bits.h:6:24: note: expanded from macro 'BIT'
This is a bug in clang that will be fixed in the future, but in order
to build cleanly with clang-8, it would be helpful to shut up this
warning. This file is the only instance reported by kernelci at the
moment.
The best solution I could come up with is to move the BIT() usage
out of the macro into the instantiation, so we can avoid using
BIT(-1).
