From mboxrd@z Thu Jan 1 00:00:00 1970 From: arvind.yadav.cs@gmail.com (Arvind Yadav) Date: Thu, 8 Dec 2016 20:05:30 +0530 Subject: [PATCH V1] pinctrl:pxa:pinctrl-pxa2xx:- No need of devm functions Message-ID: <1481207730-6332-1-git-send-email-arvind.yadav.cs@gmail.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org In functions pxa2xx_build_functions, the memory allocated for 'functions' is live within the function only. After the allocation it is immediately freed with devm_kfree. There is no need to allocate memory for 'functions' with devm function so replace devm_kcalloc with kcalloc and devm_kfree with kfree.
