+Subject: [PATCH 1/2] usb serial gadget: no TTY hangup on USB disconnect [WIP]
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+We may want to maintain the TTY over USB disconnects.
+
+This is useful when we have a terminal console to a host which
+power-cycles or for other reasons resets the USB host controller.

+Subject: [PATCH 2/2] fix Atmel maXTouch touchscreen support
+
+The Atmel maXTouch touchscreen works with Linux-libre 3.13-gnu,
+but not with the current longterm and mainline kernels in
+Parabola.
+
+Now it needs to load nonfree firmware in mxt_initialize(),
+which is in drivers/input/touchscreen/atmel_mxt_ts.c, and the
+atmel_mxt_ts driver fails to work.
+
+This driver works if changing reject_firmware_nowait to
+request_firmware_nowait in atmel_mxt_ts.c. This line is
+requesting the file named MXT_CFG_NAME, and it's a config file,
+not the firmware blob.
