From: Nicholas Bellinger Date: Tue, 9 Oct 2012 19:12:14 +0000 (-0700) Subject: qla2xxx: Add missing ->vport_slock while calling qlt_update_vp_map X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=29c08cdabd323adf7fcc0d26077383d4daf7b09a;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git qla2xxx: Add missing ->vport_slock while calling qlt_update_vp_map All other callers of qlt_update_vp_map() already hold ->vport_slock while updating the vp target map, so go ahead and add the missing ->vport_slock within qla24xx_disable_vp() code.
