+Subject: [PATCH] MIPS: ath79: simplify MISC IRQ handling
+
+commit 9c099c4e79b67d5578ce8142e6214950be4fcf43 upstream.
+
+The current code uses multiple if statements for
+demultiplexing the different interrupt sources.
+Additionally, the MISC interrupt controller has
+32 interrupt sources and the current code does not
+handles all of them.
+
+Get rid of the if statements and process all interrupt
+sources in a loop to fix these issues.
