Subject: net-sysfs: Slightly optimize 'xps_queue_show()'
X-Git-Tag: v6.1-rc5~2306^2~376
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=08a7abf4aff1a42290fd20ff7a5fa8a3ff5f90e7;p=platform%2Fkernel%2Flinux-starfive.git

net-sysfs: Slightly optimize 'xps_queue_show()'

The 'mask' bitmap is local to this function. So the non-atomic
'__set_bit()' can be used to save a few cycles.
