X-Git-Tag: v2.6.20-rc6~7
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d0f29485686d9d1c4f31240953a742d5dd4fdb72;p=linux-2.6

libata: Initialize qc->pad_len

Initialize qc->pad_len for each new command. This ensures
that pad_len is not set to a stale value for zero data
length commands.
