Subject: hw/display/sm501: Remove unneeded increment from loop
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1b336bb63e6fa6e3bc343b19725e09a55adc17b1;p=qemu.git

hw/display/sm501: Remove unneeded increment from loop

As Coverity points out (CID 1508621) the calculation to increment i in
the fill fallback loop is ineffective as it is overwritten in next
statement. This was left there by mistake from a previous version but
is not needed in the current approach so remove the superfluous
increment statement.
