I am going to push some BUG fixes for Qualcomm UFSHCI MCQ engine, one of which would count on a vops in ufshcd_send_command(). My original plan was to add a new vops.mcq_setup_xfer_req() to differentiate from the existing one used in legacy mode. But if Rohit moves the existing .setup_xfer_req() up, I can use it instead of introducing the new one.

Hi Can,

If an if-statement can be avoided in the hot path by introducing a new
callback pointer for MCQ code then I prefer the approach of introducing
a new callback instead of moving the setup_xfer_req() call.

Thanks,

Bart.
