staging: rtl8188eu: rtw_cmd: Clean up tests if NULL returned on failure
Some functions like kmalloc/kzalloc return NULL on failure. When NULL represents failure, !x is commonly used. This was done using Coccinelle: @@ expression *e; identifier l1; @@ e = \(kmalloc\|kzalloc\|kcalloc\|devm_kzalloc\)(...); ... - e == NULL + !e Signed-off-by: Bhaktipriya Shridhar <bhaktipriya96@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
