[PATCH 3/15] drivers/staging/omap-thermal/omap-bandgap.c: adjust duplicate test

[Julia Lawall]

From: Julia Lawall <Julia.Lawall@xxxxxxx>

Delete successive tests to the same location.  There was a previous test on
ret and it has not been updated since then.

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>

Perhaps it was intended to test somthing, but I am not sure what.
