From: Milan Broz Date: Thu, 10 Dec 2009 23:51:53 +0000 (+0000) Subject: dm: sysfs add empty release function to avoid debug warning X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d2bb7df8cac647b92f51fb84ae735771e7adbfa7;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git dm: sysfs add empty release function to avoid debug warning This patch just removes an unnecessary warning: kobject: 'dm': does not have a release() function, it is broken and must be fixed. The kobject is embedded in mapped device struct, so code does not need to release memory explicitly here.
