Subject: platform/x86:intel/pmc: Use the return value of pmc_core_send_msg
X-Git-Tag: v6.11-rc1~150^2~19
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=40fdf3f623041eda2a8f825d0ccd4c18f8571ffb;p=thirdparty%2Fkernel%2Flinux.git

platform/x86:intel/pmc: Use the return value of pmc_core_send_msg

Use the return value of pmc_core_send_msg() directly instead of
assigning another code when an error occurs.
