media: staging: atomisp2: cleanup null check on memory allocation
For memory allocation functions that fail with a NULL return value, it
is preferred to use the (!x) test in place of (x == NULL).
Changes in atomisp2/css2400/sh_css.c were done by hand.
Done with the help of the following cocci script:
@@
type T;
T* p;
statement s,s1;
@@
p =
\(devm_kzalloc\|devm_ioremap\|usb_alloc_urb\|alloc_netdev\|dev_alloc_skb\|
kmalloc\|kmalloc_array\|kzalloc\|kcalloc\|kmem_cache_alloc\|kmem_cache_zalloc\|
kmem_cache_alloc_node\|kmalloc_node\|kzalloc_node\|devm_kzalloc\)(...)
...when != p
if (
- p == NULL
+ !p
) s
else s1
--
Changes in v3:
Rebase changes over atomisp-next branch of the media tree
Changes in atomisp2/css2400/sh_css.c were done by hand, the above script
was not able to match the pattern if (a->b != null).
