X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=bc20589bf1c63e4e8bee57855568458ba303306b;p=openwrt%2Fstaging%2Fblogic.git

applicom.c: fix apparently-broken code in do_ac_read()

The code scriblles over a local pointer whereas it appears to be trying
to write to the memory at which that pointer points.

Addresses http://bugzilla.kernel.org/show_bug.cgi?id=11397

Nobody we know can test this change.
