From: Bjorn Helgaas Date: Mon, 28 Apr 2008 22:34:39 +0000 (-0600) Subject: PNPACPI: move _CRS/_PRS warnings closer to the action X-Git-Tag: v2.6.26-rc1~101^2^2~3 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d152cf5d0c3325979e71ee53b425fdd51a1a285a;p=linux-2.6 PNPACPI: move _CRS/_PRS warnings closer to the action Move warnings about _CRS and _PRS problems to the place where we actually make the ACPI calls. Then we don't have to pass around acpi_status values any more than necessary.
