The cfpkt_iterate() function can return -EPROTO on error, but the
function is a u16 so the negative value gets truncated to a positive
unsigned short. This causes a static checker warning.The only caller which might care is cffrml_receive(), when it's checking
the frame checksum. I modified cffrml_receive() so that it never says
-EPROTO is a valid checksum.Also this isn't ever going to be inlined so I removed the "inline".

Remove my soon bouncing email address.
Also remove the "Contact:" line in file header.
The MAINTAINERS file is a better place to find the
contact person anyway.Signed-off-by: Sjur Brændeland

We simply say that regular this_cpu use must be safe regardless of
preemption and interrupt state. That has no material change for x86
and s390 implementations of this_cpu operations. However, arches that
do not provide their own implementation for this_cpu operations will
now get code generated that disables interrupts instead of preemption.-tj: This is part of on-going percpu API cleanup. For detailed
discussion of the subject, please refer to the following thread.http://thread.gmane.org/gmane.linux.kernel/1222078

The "tmp" variable here is used to store the result of cpu_to_le16()
so it should be an __le16 instead of an int. We want the high bits
set and the current code works on little endian systems but not on
big endian systems.Signed-off-by: Dan Carpenter

Remove per site OOM messages because they duplicate
the generic mm subsystem OOM message.Use kzalloc instead of kmalloc/memset
when next to the OOM message removals.Reduces object size (allyesconfig ~2%)

This patch standardizes caif message logging prefixes.
Add #define pr_fmt(fmt) KBUILD_MODNAME ":%s(): " fmt, __func__
Add missing "\n"s to some logging messages
Convert pr_warning to pr_warnThis changes the logging message prefix from CAIF: to caif:
for all uses but caif_socket.c and chnl_net.c. Those now use
their filename without extension.Signed-off-by: Joe Perches
