From 10bcafb8ace549e7e93afa335212a8e9072c5d0c Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Thu, 21 May 2020 23:32:23 +0200 Subject: [PATCH] usb: ehci-mx6: Handle fixed regulators correctly The regulator-fixed would return -ENOSYS when enabled/disabled, because this operation is not supported, but this is not an error e.g. on systems where the VBUS cannot be controlled, so if this is the error code reported by the regulator core, consider it a success and continue.
