From 31428406bf4b9da2a322ae947096414ff0489fb5 Mon Sep 17 00:00:00 2001

Subject: [PATCH 093/102] net-next: mediatek: remove superfluous register
reads
The driver was originally written for MIPS based SoC. These required the
IRQ mask register to be read after writing it to ensure that the content
was actually applied. As this version only works on ARM based SoC, we can
safely remove the 2 reads as they ware not required.
