From: Bart Van Assche Date: Mon, 27 Apr 2015 11:52:36 +0000 (+0200) Subject: target: Remove first argument of target_{get,put}_sess_cmd() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=afc16604c06414223478df3e42301ab630b9960a;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git target: Remove first argument of target_{get,put}_sess_cmd() The first argument of these two functions is always identical to se_cmd->se_sess. Hence remove the first argument. Signed-off-by: Bart Van Assche Reviewed-by: Sagi Grimberg Reviewed-by: Christoph Hellwig Cc: Andy Grover Cc: Cc: Felipe Balbi Cc: Michael S.
