Subject: target/pscsi: Fix page increment
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=472b72f2db7831d7dbe22ffdff4adee3bd49b05d;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

target/pscsi: Fix page increment

The page++ is wrong. It makes bio_add_pc_page() pointing to a wrong page
address if the 'while (len > 0 && data_len > 0) { ... }' loop is
executed more than one once.
