3.8-stable review patch. If anyone has any objections, please let me know. ------------------ From: Julia Lawall <Julia.Lawall@xxxxxxx> [ 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> Signed-off-by: Julia Lawall <Julia.Lawall@xxxxxxx> Acked-by: Ben Hutchings <bhutchings@xxxxxxxxxxxxxx> Signed-off-by: David S.
