Subject: [SCSI] qla2xxx: Correct qla2x00_eh_wait_on_command() to wait correctly.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d970432c48ab8dd28216e80942723aeb505b623e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[SCSI] qla2xxx: Correct qla2x00_eh_wait_on_command() to wait correctly.

Original code would break-out of loop after only one iteration.
