Subject: qla2xxx: Fix sparse annotations
X-Git-Tag: omap-for-v4.3/fixes-rc1~115^2~55
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8dfa4b5a9b44714d7710f9f452f65763629f10df;p=pandora-kernel.git

qla2xxx: Fix sparse annotations

This patch removes 21 casts between an __iomem pointer type and
another data type but also introduces five new casts (see also
the casts with "__force"). Although this patch does not change
any functionality, IMHO the code with __force casts needs further
review.
