rtlwifi: rtl8192ce: rtl8192cu: Fix endian issue
Commit e996db69833a (rtlwifi: rtl8192c: Add init codes for "fw_version" and "fw_subversion") added initialization for fw_version, but failed to note that the variable in the firmware header is little-endian. The following Sparse warning results: CHECK drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c:242:36: warning: incorrect type in assignment (different base types) drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c:242:36: expected unsigned short [unsigned] [usertype] fw_version drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c:242:36: got restricted __le16 [usertype] version When fixing this problem, I noticed that several of the drivers contain nearly identical copies of the firmware header struct, and that only the one used in rtl8192c{e,u} had correct endian notation. The struct has been moved into a common header, and the other drivers will be fixed in subsequant patches.
