[PATCH 04/16] staging: wilc1000: pass struct wilc to the functions which use hif_func
Glen Lee

Wed Nov 18 06:11:25 UTC 2015
This patch passes struct wilc to the functions which use hif_func inside.
The function pointers of wilc_hif_func will pass wilc also in the later
patch. Pass wilc to the functions if necessary.
Flollowings are modified functions.
chip_wakeup
wilc_chip_sleep_manually
chip_allow_sleep
wilc_get_chipid
wilc_unknown_isr_ext
wilc_pllupdate_isr_ext
wilc_sleeptimer_isr_ext
