drivers/char/mxser.c: fix compilation warning in mxser.c
Both mxser_disable_must_enchance_mode() and mxser_get_must_hardware_id() called from function CheckIsMoxaMust(), when CONFIG_PCI=y. So mark both the functions under CONFIG_PCI. We were warned by the following warning. drivers/char/mxser.c:306: warning: `mxser_disable_must_enchance_mode' defined but not used drivers/char/mxser.c:391: warning: `mxser_get_must_hardware_id' defined but not used Signed-off-by: Rakib Mullick <rakib.mullick@gmail.com> Cc: Jiri Slaby <jirislaby@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
