Subject: staging: csr: remove func_enter macro
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=438d2d1329914da8fdf3a8aedac8ce7e5ffad26d;p=linux-beck.git

staging: csr: remove func_enter macro

this macro is used for debugging purposes,

it actually defined as

if (unifi_debug >= 5) {
	printk("unifi => %s\n", __FUNCTION__);
}

which produces too many of those prints if the unifi_debug is >=5.
remove these calls and the macro itself altogether
