Subject: dm9000: remove redundant ISR status clear
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=36259012a4ba34d70d4fe0e8533980919e8b6024;p=deliverable%2Flinux.git

dm9000: remove redundant ISR status clear

Since dm9000_interrupt() is already reading/clearing every set bit in
DM9000_ISR, this additional clear in dm9000_rx() (which is only called
by dm9000_interrupt()) is unnecessary and can be removed.
