Subject: ACPICA: Resources: Fix loop termination for the get AML length function.
X-Git-Tag: v3.13-rc2~19^2~2^2~4
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9a0a35972591f91167556b4a61673d08ef07f310;p=pandora-kernel.git

ACPICA: Resources: Fix loop termination for the get AML length function.

The loop terminates on a NULL resource pointer, which can never
happen since the loop simply increments a valid resource pointer.
This fix changes the loop to terminate on an end-of-buffer condition.

Problem can be seen by callers to AcpiSetCurrentResources with an
invalid or corrupted resource descriptor; or a resource descriptor
without an END_TAG descriptor.
