** Description changed:
+ [SRU Justification]
+
+ [Impact]
+
+ Upstream commit 0edb555a65d1e ("platform: Make platform_driver::remove()
+ return void") fails the build against linux-6.11.
+
+ [Fix]
+
+ An upstream usbio release WW3224-USBIO-PV-HFIX1 carries the fix.
+
+ [Test Case]
+
+ Install the built dkms binary package and linux-headers-
+ oem-24.04b/noble. The dkms build should be triggered and complete
+ successfully.
+
+ [Where problems could occur]
+
+ It appears the i2c protocol meant to be governed by this usbio is not in
+ well control by the upstream collaborative peers, such that we fell into
+ various problems due the the mismatch of firmware version, and therefore
+ some ugly patch from Intel was added to work-around that. While we don't
+ have too much details about the design and the solution, all we can do
+ is to deploy extensive tests as possible.
+
+ [Other Info]
+
+ The SRU collects fixes for a few bugs:
+ * bug 2076263: meant for series with kernel >= 6.11, therefore Noble and
Oracular,
+ * bug 2060101: meant for hwe-6.8 and on, therefore Noble and Oracular,
+ * bug 2071821: meant for IPU7 platforms, therefore Oracular only (which will
be compiled in linux/oracular and linux-oem-6.11/noble)
