From: Arnd Bergmann Date: Wed, 26 Jul 2023 11:49:36 +0000 (+0200) Subject: genpd: move owl-sps-helper.c from drivers/soc X-Git-Tag: v6.6-rc1~134^2~10 X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=7ed363cd8d0a3e4fbe3c37b7458420f82ef9a106;p=linux-block.git genpd: move owl-sps-helper.c from drivers/soc Moving only one of the two files in drivers/soc/actions to drivers/genpd caused a link failure in allmodconfig, as drivers/genpd is entered for compile testing, but drivers/soc/actions accidentally got skipped: x86_64-linux-gnu-ld: vmlinux.o: in function `owl_sps_set_power': owl-sps.c:(.text+0x16e259d): undefined reference to `owl_sps_set_pg' Move the other one as well to allow build testing to work correctly.
