If anyone has any objections, please let me know. ------------------ From: Manish Rangankar [ Upstream commit 5cbc49d5c4cd20c18041e86958103045216d2190 ] qla2x00_sysfs_read_vpd() called ha->isp_ops->read_optrom() a second time after releasing optrom_mutex. The repeated read is redundant and, unlike the first, runs without optrom_mutex held, exposing flash access to concurrent optrom operations. Drop the duplicate call.
