staging: rtl8723au: core: avoid bitwise arithmetic with forced endianness
This fixes bitwise arithmetic performed on the host on a variable previously converted to little-endian, and subsequently converted again to little-endian: - issue_action_BA23a() called with "status" crafted in host byte order - "status" converted to LE - bitwise arithmetic on the (LE) "status", performed with masks and shifts in host byte order - result converted to LE (again) and stored in device structure Sparse warning addressed by this patch: drivers/staging/rtl8723au/core/rtw_mlme_ext.c:3806:16: warning: incorrect type in assignment (different base types) drivers/staging/rtl8723au/core/rtw_mlme_ext.c:3806:16: expected unsigned short [unsigned] status drivers/staging/rtl8723au/core/rtw_mlme_ext.c:3806:16: got restricted __le16 [usertype] <noident> Additional notes: initial cpu_to_le16 was introduced by kernel bulk commit 5e93f352 "staging: r8723au: Add source files for new driver - part 1", initially from github according to commit description. On github, this traces back to another bulk commit: 2896bda04353 "Add new files in core directory", which is the 1st version of the driver.
