Staging: cpc-usb: Adjust NULL test
Since card must already be non-NULL, it seems that what was intended was to test the result of kmalloc. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression E,E1; identifier f,fld,fld1; statement S1,S2; @@ E->fld = f(...); ... when != E = E1 when != E->fld1 = E1 if ( - E + E->fld == NULL) S1 else S2 // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
