Subject: [PATCH] ACPI: fix test for hex digit.
Date: Thu, 31 Jul 2014 01:22:12 +0530 [thread overview]
Message-ID: <1406749932-1709-1-git-send-email-arjun024@gmail.com> (raw)
decimal 0 is ascii for NULL. Hex digit matching should be from '0'
(decimal 30 of ascii) to '9' and 'A' to 'F'.
Unfixed version returns true for #,$,%,& etc.
