Subject: target: Correct transport_wait_for_tasks() documentation
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2d4760ee4720d5f0eeda770ce248244166676283;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

target: Correct transport_wait_for_tasks() documentation

transport_wait_for_tasks() not only waits for command completion
but also sets CMD_T_STOP. Additionally, this function is not only
called by frontend drivers but also by the target core. Update
the transport_wait_for_tasks() documentation to reflect this.
