Silva" Date: Mon, 11 Oct 2021 21:46:24 -0500 Subject: [PATCH] staging: r8188eu: Use zeroing allocator in wpa_set_encryption() [ Upstream commit c82462f124df06a0a34793f1a1dafe5c146a2a6f ] Use zeroing allocator rather than allocator followed by memset with 0. This issue was detected with the help of Coccinelle. Signed-off-by: Gustavo A. R.
