Subject: target: call transport_check_aborted_status from target_execute_cmd
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d59a02b4ebe6fe5ac42b702f1ced6368ced78d76;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

target: call transport_check_aborted_status from target_execute_cmd

When we call target_execute_cmd for write commands the command has been
on the state list before an abort might have come in before
target_execute_cmd.  Call transport_check_aborted_status to deal with
this case.
