This patch seems to cause several warnings along the lines of:

drivers/net/wireless/intersil/hostap/hostap_hw.c: In function ‘prism2_init_local_data’:
drivers/net/wireless/intersil/hostap/hostap_hw.c:3185:48: warning: cast between incompatible function types from ‘void (*)(struct tasklet_struct *)’ to ‘void (*)(long unsigned int)’ [-Wcast-function-type]
3185 | do { memset((q), 0, sizeof(*(q))); (q)->func = (void(*)(unsigned long))(f); } | ^
drivers/net/wireless/intersil/hostap/hostap_hw.c:3187:2: note: in expansion of macro ‘HOSTAP_TASKLET_INIT’
