From mboxrd@z Thu Jan 1 00:00:00 1970 From: k.kozlowski@samsung.com (Krzysztof Kozlowski) Date: Thu, 16 Oct 2014 09:42:00 +0200 Subject: [PATCH v2 0/7] power_supply: Decrement the device reference counter Message-ID: <1413445327-24862-1-git-send-email-k.kozlowski@samsung.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Hi, Changes since v1: ================= 1. Remove check for non-NULL in power_supply_put (suggested by Pavel Machek). 2. Add Pavel Machek's ack. Description: ============ The reference counter of device allocated for power supply was incremented with each call to power_supply_get_by_name() and power_supply_get_by_phandle(). Add a symmetric 'put' operation so the device could be released after final put_device() call during supply unregistering. Rebased on next-20141007 + mine [1] patchset. Tested on Trats2 board (max77693 + charger manager). Kindly asking for reviewing and testing other drivers.
