Subject: [PATCH AUTOSEL 5.15 8/9] scsi: lpfc: Fix incorrect big endian type assignment in bsg loopback path
From: Justin Tee <justintee8345@...il.com>
[ Upstream commit 9cefd6e7e0a77b0fbca5c793f6fb6821b0962775 ]
The kernel test robot reported sparse warnings regarding incorrect type
assignment for __be16 variables in bsg loopback path.
Change the flagged lines to use the be16_to_cpu() and cpu_to_be16() macros
appropriately.
