drivers/ipack/devices/ipoctal.c: adjust duplicate test
Delete successive tests to the same location. The code tested the result
of a previous allocation, that itself was already tested. It is changed to
test the result of the most recent allocation.
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>
