Subject: serial,mfd: Fix CMSPAR setup
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=604fdb75094a7367e1794fd0f62183380364ce13;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

serial,mfd: Fix CMSPAR setup

This is referenced the wrong way. Mika Westerberg added some checks to the
tty to support multiple console, but the real problem is simply referencing the
termios object via the wrong path.
