Subject: Remove redundant members of struct acm
X-Git-Url: https://git.decadent.org.uk/gitweb/?p=exar-uart-driver.git;a=commitdiff_plain;h=68fc20fade2c8755352f708d4e3e28883cbc7c75

Remove redundant members of struct acm

preciseflags is always zero since removing the custom ioctls.

trans9 is only used in acm_tty_set_termios() and is recalculated each
time.
