Subject: [PATCH v2 4/6] drivers: hv: vmbus: Fix checkpatch SPLIT_STRING
Date: Tue, 24 Nov 2020 23:14:03 -0300 [thread overview]
Message-ID: <20201125021403.3621-1-matheus@castello.eng.br> (raw)
Checkpatch emits WARNING: quoted string split across lines.
To keep the code clean and with the 80 column length indentation the
check and registration code for kmsg_dump_register has been transferred
to a new function hv_kmsg_dump_register.
Signed-off-by: Matheus Castello <matheus@castello.eng.br>

This is the V2 of patch 4 of the series "Add improvements suggested by
checkpatch for vmbus_drv" with the changes suggested by Michael Kelley
