Subject: [PATCH 5.4 035/177] usb: common: usb-conn-gpio: Dont log an error on probe deferral
Date: Mon, 16 Dec 2019 18:48:11 +0100 [thread overview]
Message-ID: <20191216174828.552457581@linuxfoundation.org> (raw)
In-Reply-To: <20191216174811.158424118@linuxfoundation.org>
From: Bryan O'Donoghue <bryan.odonoghue@linaro.org>
commit 59120962e4be4f72be537adb17da6881c4b3797c upstream.
This patch makes the printout of the error message for failing to get a
VBUS regulator handle conditional on the error code being something other
than -EPROBE_DEFER.
Deferral is a normal thing, we don't need an error message for this.
