Subject: 'flags' in rsparser.c change from 'register disabled resources' patch
Date: Mon, 22 Aug 2011 01:59:02 +0100 [thread overview]
Message-ID: <20110822005902.GA30602@gallifrey> (raw)
Hi Witold,
'sparse' is giving me the following set of warnings in the latest
kernel:
CHECK drivers/pnp/pnpacpi/rsparser.c
drivers/pnp/pnpacpi/rsparser.c:515:26: warning: cast truncates bits from constant value (10000000 becomes 0)

drivers/pnp/pnpacpi/rsparser.c:682:26: warning: cast truncates bits from constant value (10000000 becomes 0)
these all seem to come from the 'flags' variables you added
as part of patch 29df8d8f being char's and IORESOURCE_DISABLED
being 0x10000000 so lines like:
+ unsigned char flags = 0;
+ flags |= IORESOURCE_DISABLED;
shouldn't work.
Dave
