param: convert some "on"/"off" users to strtobool
This changes several users of manual "on"/"off" parsing to use strtobool. Some side-effects: - these uses will now parse y/n/1/0 meaningfully too - the early_param uses will now bubble up parse errors Signed-off-by: Kees Cook <keescook@chromium.org> Acked-by: Heiko Carstens <heiko.carstens@de.ibm.com> Acked-by: Michael Ellerman <mpe@ellerman.id.au> Cc: Amitkumar Karwar <akarwar@marvell.com> Cc: Andy Shevchenko <andy.shevchenko@gmail.com> Cc: Daniel Borkmann <daniel@iogearbox.net> Cc: Joe Perches <joe@perches.com> Cc: Kalle Valo <kvalo@codeaurora.org> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Cc: Nishant Sarmukadam <nishants@marvell.com> Cc: Rasmus Villemoes <linux@rasmusvillemoes.dk> Cc: Steve French <sfrench@samba.org> Cc: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
