From 5b48bec5f6c818b7e4ca7c7ae7d7adfa742e9913 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Wed, 19 Dec 2018 16:30:07 +0000 Subject: [PATCH] staging: wilc1000: fix missing read_write setting when reading data commit c58eef061dda7d843dcc0ad6fea7e597d4c377c0 upstream. Currently the cmd.read_write setting is not initialized so it contains garbage from the stack. Fix this by setting it to 0 to indicate a read is required.
