[patch 2.6.15-mm4] drivers/cdrom/cdrom.c fix incorrect test

From: Benoit Boissinot
Date: Sat Jan 14 2006 - 17:52:04 EST


In cleanup-cdrom_ioctl.patch,

the test in CDROMREADTOCENTRY ioctl was changed from

if (!((requested_format == CDROM_MSF) || (requested_format == CDROM_LBA)))
return -EINVAL;

to

if (requested_format != CDROM_MSF || requested_format != CDROM_LBA)
return -EINVAL;


which is not equivalent with morgan's law.
