[PATCH] protect ide_cdrom_capacity by ifdef
The only call to ide_cdrom_capacity is in code protected by CONFIG_PROC_FS, so when that is not enabled, the compiler complains: drivers/ide/ide-cd.c:3259: warning: `ide_cdrom_capacity' defined but not used Here is a patch that fixes that. It provides some space savings for embedded systems that are not using procfs, as well: text data bss dec hex filename - 33540 6504 1032 41076 a074 drivers/ide/ide-cd.o + 33468 6480 1032 40980 a014 drivers/ide/ide-cd.o Signed-off-by: Amos Waterland <apw@us.ibm.com> Cc: Jens Axboe <axboe@suse.de> Cc: Bartlomiej Zolnierkiewicz <B.Zolnierkiewicz@elka.pw.edu.pl> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
