Staging: rtl8723au: Remove print statements and debug messages
Author: Bhumika Goyal <bhumirks@gmail.com>
The memory allocation functions generates a call stack containing
all the context information on failure, so print statements and debug
messages can be removed on failure of these functions. Also remove
unwanted {} around if block after removal of these messages.
Done using coccinelle:
@@
expression e;
@@
e=\(kmalloc\|kmalloc\|kmalloc_array\|alloc_netdev\|kzalloc\|
devm_kzalloc\|devm_ioremap\)(...);
...
if(!e){
- \(DBG_8723A\|printk\|pr_err\|CERROR\|DBG_88E\)(...);
...when any
}
