From: André Draszik Date: Tue, 4 Mar 2025 17:05:33 +0000 (+0000) Subject: rtc: ep93xx: drop needless struct ep93xx_rtc::rtc member X-Git-Tag: v6.15-rc1~33^2~34 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5d0ad519f503b8432ebc396dfe87e6190dbdcbb1;p=thirdparty%2Flinux.git rtc: ep93xx: drop needless struct ep93xx_rtc::rtc member The memory pointed to by the ::rtc member is managed via devres, and no code in this driver uses it past _probe(). We can drop it from the structure and just use a local temporary variable, reducing runtime memory consumption by a few bytes.
