[trivial PATCH 00/15] remove duplicate unlikely from IS_ERR

From: Joe Perches
Date: Thu Dec 09 2010 - 15:05:37 EST


Tobias Klauser <tklauser@xxxxxxxxxx> sent a patch to remove
an unnecessary unlikely from drivers/misc/c2port/core.c,
https://lkml.org/lkml/2010/12/9/199

Here are the other instances treewide.

I think it'd be good if people would, when noticing defects in a
specific subsystem, look for and correct the same defect treewide.

IS_ERR already has an unlikely test so remove unnecessary
unlikelys from the call sites.

from: include/linux/err.h
#define IS_ERR_VALUE(x) unlikely((x) >= (unsigned long)-MAX_ERRNO)
[...]
static inline long __must_check IS_ERR(const void *ptr)
{
return IS_ERR_VALUE((unsigned long)ptr);
}

Sending directly to maintainers for now, will resend in a month
or so only to trivial if not picked up.
