+Subject: lightnvm: initialize ppa_addr in dev_to_generic_addr()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Javier González <javier@cnexlabs.com>
+
+commit 5389a1dfb39786df08d4f6a482bd2734b1b50e33 upstream.
+
+The ->reserved bit is not initialized when allocated on stack.
+This may lead targets to misinterpret the PPA as cached.

+Subject: p54: memset(0) whole array
+
+From: Jiri Slaby <jslaby@suse.cz>
+
+commit 6f17581788206444cbbcdbc107498f85e9765e3d upstream.
+
+gcc 7 complains:
+drivers/net/wireless/intersil/p54/fwio.c: In function 'p54_scan':
+drivers/net/wireless/intersil/p54/fwio.c:491:4: warning: 'memset' used with length equal to number of elements without multiplication by element size [-Wmemset-elt-size]
+
+Fix that by passing the correct size to memset.
