Staging: rtl8723bs: proposed patchset: remove useless structs

Staging: rtl8723bs: proposed patchset: remove useless structs

[Marco Cesati]

The staging/rtl8723bs driver code includes 83 unnecessary struct
definitions (never referenced in the code). Here there are:

cfg80211_wifidirect_info tdls_info tdls_txmgmt P2P_PS_Offload_t
P2P_PS_CTWPeriod_t usb_suspend_parm getbasicrate_rsp getdatarate_rsp
readBB_parm readBB_rsp readTSSI_parm readTSSI_rsp writeBB_parm
readRF_parm readRF_rsp writeRF_parm getrfintfs_parm settxagctbl_parm
gettxagctbl_parm gettxagctbl_rsp setagcctrl_parm setssup_parm
getssup_parm getssup_rsp setssdlevel_parm getssdlevel_parm

ieee80211_softmac_stats ieee80211_security ieee80211_header_data
phy_status_rpt_8812_t odm_sta_info_t odm_ra_info_t

Should I submit a patchset that removes all of these definitions?

Best regards,

Marco

Yeah.  Delete anything that isn't used.

Once in a while we have stuff like:

#define enable  0x1
#define disable 0x2
#define reset   0x3

So it's like a list of commands that we pass to the hardware.  And maybe
we never use the reset command.  But it's still useful to know that it's
0x3 so the unused define serves as hardware documentation.

But this sort of define as hardware documentation isn't common.
Generally if something isn't used, then delete it.
