X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2cbff556f2e153af48564b125711417b7e6dc6ad;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

scsi: qla2xxx: Initialize port speed to avoid setting lower speed

commit f635e48e866ee1a47d2d42ce012fdcc07bf55853 upstream.

This patch initializes port speed so that firmware does not set lower
operating speed. Setting lower speed in firmware impacts WRITE perfomance.
