From: Andy Shevchenko Date: Mon, 19 Feb 2024 15:04:57 +0000 (+0200) Subject: serial: 8250_exar: Don't remove GPIO device on suspend X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=d2b48ecc760ae540b298bcf88a050c8bceef9662;p=people%2Faperard%2Flinux.git serial: 8250_exar: Don't remove GPIO device on suspend [ Upstream commit 73b5a5c00be39e23b194bad10e1ea8bb73eee176 ] It seems a copy&paste mistake that suspend callback removes the GPIO device. There is no counterpart of this action, means once suspended there is no more GPIO device available untile full unbind-bind cycle is performed. Remove suspicious GPIO device removal in suspend.
