+Subject: [PATCH] Bluetooth: Fix l2cap_sock_setsockopt() with optname BT_RCVMTU
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+commit 23bc6ab0a0912146fd674a0becc758c3162baabc upstream.
+
+When we retrieve imtu value from userspace we should use 16 bit pointer
+cast instead of 32 as it's defined that way in headers. Fixes setsockopt
+calls on big-endian platforms.
