X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b5749fe182a0fa1c39ea1b33c0691d436f269195;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git scsi: lpfc: Fix Xlane dynamic LUN set for LUN priority. Fix Xlane dynamic LUN set for LUN priority. Dynamic changing of the priority was not getting reflected on the LUN.
