Date: Mon, 13 Sep 2021 15:14:38 +0200 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Sergey Shtylyov <s.shtylyov@...russia.ru>, Ard Biesheuvel <ardb@...nel.org>, Wolfram Sang <wsa@...nel.org>, Sasha Levin <sashal@...nel.org> Subject: [PATCH 5.14 224/334] i2c: synquacer: fix deferred probing From: Sergey Shtylyov <s.shtylyov@....ru> [ Upstream commit 8d744da241b81f4211f4813b0d3c1981326fa9ca ] The driver overrides the error codes returned by platform_get_irq() to -ENODEV, so if it returns -EPROBE_DEFER, the driver will fail the probe permanently instead of the deferred probing. Switch to propagating the error codes upstream.
