We get 3 warnings when building kernel with W=1:
drivers/staging/ks7010/ks7010_sdio.c:90:6: warning: no previous prototype for
'ks_wlan_hw_sleep_doze_request' [-Wmissing-prototypes]
drivers/staging/ks7010/ks7010_sdio.c:121:6: warning: no previous prototype for
'ks_wlan_hw_sleep_wakeup_request' [-Wmissing-prototypes]
drivers/staging/ks7010/ks7010_sdio.c:174:5: warning: no previous prototype for
'_ks_wlan_hw_power_save' [-Wmissing-prototypes]
In fact, these functions are only used in the file in which they are
declared and don't need a declaration, but can be made static.
so this patch marks these functions with 'static'.
