Subject: [PATCH] net: sysfs: cleanup coding style
Date: Sun, 28 Jun 2026 20:58:24 +0200 [thread overview]
Message-ID: <20260628185824.231250-1-lucasp.linux@gmail.com> (raw)
Replace DEVICE_ATTR() with DEVICE_ATTR_RW() where applicable to
follow kernel coding style conventions. Add blank lines between
function definitions and macro invocations. Fold multi-line
attribute initializations onto single lines where it improves
readability without exceeding the line length limit.
