From 0f24cd7062cdb9e45cb05265fa1b9fc619c56084 Mon Sep 17 00:00:00 2001 From: Vaishali Thakkar Date: Fri, 31 Oct 2014 08:41:42 +0530 Subject: [PATCH] Staging: rtl8192e: Use put_unaligned_le16 This patch introduces the use of function put_unaligned_le16. This is done using Coccinelle and semantic patch used is as follows: @@ identifier tmp; expression ptr; expression y,e; type T; @@ - tmp = cpu_to_le16(y); <+... when != tmp - memcpy(ptr, (T)&tmp, ...); + put_unaligned_le16(y,ptr); ...+> ? tmp = e @@ type T; identifier tmp; @@ - T tmp; ...when != tmp Here, to be compatible with the change header file is added too.
