- 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.
