+
+Without this there was a double free of the metadata,
+which ended up freeing the fd table for me here, and taking
+out the machine more often than not.
+
+I reproduced with X.org + modesetting DDX + latest llvm/mesa,

+Subject: gpu: ipu-v3: Fix imx-ipuv3-crtc module autoloading
+
+From: Philipp Zabel <p.zabel@pengutronix.de>
+
+commit 503fe87bd0a8346ba9d8b7f49115dcd0a4185226 upstream.
+
+If of_node is set before calling platform_device_add, the driver core
+will try to use of: modalias matching, which fails because the device
+tree nodes don't have a compatible property set. This patch fixes
+imx-ipuv3-crtc module autoloading by setting the of_node property only
+after the platform modalias is set.
+
+Fixes: 304e6be652e2 ("gpu: ipu-v3: Assign of_node of child platform devices to corresponding ports")

+Subject: iio: ak8975: fix maybe-uninitialized warning
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Richard Leitner <dev@g0hl1n.net>
+
+commit 05be8d4101d960bad271d32b4f6096af1ccb1534 upstream.
+
+If i2c_device_id *id is NULL and acpi_match_device returns NULL too,
+then chipset may be unitialized when accessing &ak_def_array[chipset] in
+ak8975_probe. Therefore initialize chipset to AK_MAX_TYPE, which will
+return an error when not changed.
+
+This patch fixes the following maybe-uninitialized warning:
+
+drivers/iio/magnetometer/ak8975.c: In function ‘ak8975_probe’:
+drivers/iio/magnetometer/ak8975.c:788:14: warning: ‘chipset’ may be used
+uninitialized in this function [-Wmaybe-uninitialized]
+ data->def = &ak_def_array[chipset];

+In certain probe conditions the interrupt came right after registering
+the handler causing a NULL pointer exception because of uninitialized
