Subject: target: Make core_tmr_abort_task() consider all commands
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3a1e7ca64f2dae69536054c42b7b90e480db1045;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

target: Make core_tmr_abort_task() consider all commands

It is possible that two commands with the same tag are present on
sess_cmd_list because commands are removed from sess_cmd_list after
a response has been sent to the initiator. Hence continue searching
through sess_cmd_list even if a matching tag has already been found.
