From: Andy Shevchenko Date: Mon, 25 Jan 2021 19:39:43 +0000 (+0200) Subject: x86/platform/intel-mid: Remove unused leftovers (msic_power_btn) X-Git-Tag: v5.15~1647^2~14 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4450e93fea0c92c0838e9df30e95f2eb5f68226a;p=platform%2Fkernel%2Flinux-starfive.git x86/platform/intel-mid: Remove unused leftovers (msic_power_btn) There is no driver present, remove the device creation and other leftovers. Note, for Intel Merrifield there is another driver which is instantiated by a certain MFD one and does not need any support from device_libs.
