Subject: drivers/net/ethernet/sfc/ptp.c: adjust duplicate test


From: Julia Lawall <Julia.Lawall@lip6.fr>

[ Upstream commit 56567c6f8751c633581ca7c8e1cf08eed503f5ea ]

Delete successive tests to the same location.  rc was previously tested and
not subsequently updated.  efx_phc_adjtime can return an error code, so the
call is updated so that is tested instead.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@s exists@
local idexpression y;
expression x,e;
@@

*if ( \(x == NULL\|IS_ERR(x)\|y != 0\) )
 { ... when forall
   return ...; }
... when != \(y = e\|y += e\|y -= e\|y |= e\|y &= e\|y++\|y--\|&y\)
    when != \(XT_GETPAGE(...,y)\|WMI_CMD_BUF(...)\)
*if ( \(x == NULL\|IS_ERR(x)\|y != 0\) )
 { ... when forall
   return ...; }
// </smpl>
