Subject: OMAP3: McBSP: Use the port's buffer_size when calculating tx delay
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f10b8ad15f9531b6d58edabccf05e9eb738c4409;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

OMAP3: McBSP: Use the port's buffer_size when calculating tx delay

Sicne the platform data's buffer_size now holds the full size
of the FIFO, there is no longer need to handle the ports
differently.
