Julien Brunel 71dc525c5d ALSA: sound/soc/at32: Useless NULL test ... The test (ssc != NULL) can only be reached if the call to the function ssc_request, the result of which ssc is assigned, succeeds. Moreover, two statements assign NULL to ssc just before a return, which is useless since it is a local variable. So, we suggest to delete the test and the two assignments. A simplified version of the semantic match that finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @bad_null_test@ expression x,E; @@ x = ssc_request(...) ... when != x = E * x != NULL // </smpl> Signed-off-by: Julien Brunel <brunel@diku.dk> Signed-off-by: Julia Lawall <julia@diku.dk> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>		2008-10-10 13:41:40 +02:00
