Subject: staging: rtl8723au: change parameter type in rtl8723a_set_rssi_cmd declaration
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=485b099ad8c0a9ad5c856bef60017faa5178e744;p=linux-beck.git

staging: rtl8723au: change parameter type in rtl8723a_set_rssi_cmd declaration

Previosly the function had the following prototype:
int rtl8723a_set_rssi_cmd(struct rtw_adapter *padapter, u8 *param)

My suggestion here is to modify the prototype this way:
int rtl8723a_set_rssi_cmd(struct rtw_adapter *padapter, u32 param)

We can do this based on the following considerations:
1. rtl8723a_set_rssi_cmd is used only with 32-bit "param" values
2. There's no point in using "u8 *param" until we pass param length
3. As we just read "param", it's ok to pass it by value
