From a57adacf50d1bc0b5efd85b484a5c52a4c1ebcf1 Mon Sep 17 00:00:00 2001 From: Svyatoslav Ryhel Date: Mon, 20 Mar 2023 21:01:43 +0200 Subject: cmd: ums: abort mounting by pressing any key This patch introduses config which allows interrupt run of usb mass storage with any key. This is especially useful on devices with limited input capabilities like tablets and smatphones which have only gpio keys in direct access.
