Subject: vme: vme_tsi148.c: fix to use list_for_each_safe() when delete list items
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b49c32ba2ca3b51ddbb863ff139adca6b85b7543;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

vme: vme_tsi148.c: fix to use list_for_each_safe() when delete list items

Since we will be removing items off the list using list_del() we need
to use a safer version of the list_for_each() macro aptly named
list_for_each_safe().
