Date: Wed, 12 Feb 2014 10:51:41 +0100 From: Krzysztof Kozlowski <k.kozlowski@...sung.com> To: Samuel Ortiz <sameo@...ux.intel.com>, Lee Jones <lee.jones@...aro.org>, linux-kernel@...r.kernel.org Cc: Krzysztof Kozlowski <k.kozlowski@...sung.com>, stable@...r.kernel.org Subject: [PATCH] mfd: 88pm800: Fix I2C device resource leak if probe fails During probe the driver allocates two dummy I2C devices for subchips in function pm800_pages_init(). Additionally this function allocates regmaps for these subchips. If any of these steps fail then these dummy I2C devices are not freed and resources leak. On pm800_pages_init() fail the driver must call pm800_pages_exit() to unregister dummy I2C devices.
