From b8d25dee3b73b572ea1778671098ee7b943133c5 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Fri, 1 Feb 2008 23:09:19 +0100 Subject: [PATCH] ide-cd: remove needless zeroing of 'info' fields from ide_cdrom_setup() ide_cd_probe() zeroes 'info' prior to calling ide_cdrom_setup() so there is no need to explicitly zero 'info' fields in the latter function. Ditto for fields of CDROM_STATE_FLAGS(), CDROM_CONFIG_FLAGS() and 'cdi' (all are embedded in 'info').
