Subject[PATCH V1] pinctrl:pxa:pinctrl-pxa2xx:- No need of devm functions
Date
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.
