Subject: ia64: select CONFIG_TTY for use of tty_write_message in unaligned
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6035d9db386bf30151ed16a94c9223bbe52562ee;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ia64: select CONFIG_TTY for use of tty_write_message in unaligned

Fix breakage which will be exposed by the patch "kconfig: make allnoconfig
disable options behind EMBEDDED and EXPERT".

arch/ia64/kernel/unaligned.c uses tty_write_message to print an
unaligned access exception to the TTY of the current user process.
Enable TTY to prevent a build error.

Minimal fix, on the basis that few people on ia64 will care deeply about
kernel size enough to turn off TTY.  Ideally, I'd instead suggest
dropping the tty_write_message entirely, and just leaving the printk.
Bonus: no need to sprintf first.
