From mboxrd@z Thu Jan 1 00:00:00 1970 From: leonard.crestez@nxp.com (Leonard Crestez) Date: Fri, 31 Mar 2017 22:25:36 +0300 Subject: [PATCH 1/5] ARM: imx: gpc: Do not print error message for EPROBE_DEFER In-Reply-To: References: Message-ID: To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The pu regulator request will return -EPROBE_DEFER if it has a supply from PMIC and this supply is not yet registered. This does not represent an error since the driver will call probe again later, so only print a warning message in this case.
