Subject: [NET]: Fix net/socket.c warnings.
X-Git-Tag: v2.6.21-rc1~83^2~65^2~3
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4387ff75f29412a234d394b0276c2b239d3d3844;p=pandora-kernel.git

[NET]: Fix net/socket.c warnings.

GCC (correctly) says:

net/socket.c: In function ‘sys_sendto’:
net/socket.c:1510: warning: ‘err’ may be used uninitialized in this function
net/socket.c: In function ‘sys_recvfrom’:
net/socket.c:1571: warning: ‘err’ may be used uninitialized in this function

sock_from_file() either returns filp->private_data or it
sets *err and returns NULL.

Callers return "err" on NULL, but filp->private_data could
be NULL.

Some minor rearrangements of error handling in sys_sendto
and sys_recvfrom solves the issue.
