+Subject: [PATCH] i2c: brcmstb: fix support for DSL and CM variants
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+DSL and CM (Cable Modem) support 8 B max transfer size and have a custom
+DT binding for that reason. This driver was checking for a wrong
+"compatible" however which resulted in an incorrect setup.
+
+Fixes: e2e5a2c61837 ("i2c: brcmstb: Adding support for CM and DSL SoCs")
