Subject: tty: use const parameters in port-flag accessors
X-Git-Tag: v5.11-rc1~166^2~8
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=9e1792727ead477f49958578d0dbd466a7deea48;p=thirdparty%2Fkernel%2Flinux.git

tty: use const parameters in port-flag accessors

Declare the port parameter to the flag-test accessors as const.

This is currently mostly cosmetic as the accessors are already inlined.
