Subject: Remove msic_dcr_read() in axon_msi.c
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2843e7f7d6ffd61da6fe1503eb42c25fa33fbfee;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

Remove msic_dcr_read() in axon_msi.c

msic_dcr_read() doesn't really do anything useful, just replace it with
direct calls to dcr_read().
