[PATCH 3/3] PCI hotplug: remove assignement from if conditions

From: Quentin Lambert
Date: Mon Aug 04 2014 - 15:02:04 EST


The following Coccinelle semantic patch was used to
find and correct cases of assignements in if conditions:

@ifassign@
expression var, expr;
statement S;
@@

- if(!(var = expr)) S
+ var = expr;
+ if(!var) S
