Subject: [PATCH net-next 02/11] net: hostap: fix function cast warning

From: Arnd Bergmann <arnd@...db.de>

gcc -Wextra complains about the function type cast:

drivers/net/wireless/intersil/hostap/hostap_hw.c:3173:48: warning: cast between incompatible function types from ‘void (*)(struct tasklet_struct *)’ to ‘void (*)(long unsigned int)’ [-Wcast-function-type]

Avoid this by just using the regular tasklet_setup() function instead
of the incorrect homegrown version.

Fixes: 7433c9690318 ("intersil: convert tasklets to use new tasklet_setup() API")
