From 87e858a97e8a7010aedc01db7cd31cc7c02b0b6a Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Wed, 28 Dec 2011 18:47:46 +0200 Subject: mtd: do not use mtd->get_*_prot_info directly Instead, call 'mtd_get_*_prot_info()' and check for '-EOPNOTSUPP'. While on it, fix the return code from '-EOPNOTSUPP' to '-EINVAL' for the case when the mode parameter is invalid.
