fw.c contains a function for loading the firmware. led.c contains a function for controlling the LED. Signed-off-by: Bitterblue Smith <rtl8821cerfe2@gmail.com> --- v6: - Update copyright year. - Remove some unused includes. - Make all functions use the prefix "rtl92du". v5: - No change. v4: - Fix fw.h and led.h header guards. - Add empty lines. - Delete globalmutex_for_fwdownload and simplify rtl92d_download_fw. It can't run in parallel because mutex_for_hw_init in rtl92du_hw_init protects the entire function. v3: - No change. v2: - Patch is new in v2, split from patch 3/3 in v1. --- .../wireless/realtek/rtlwifi/rtl8192du/fw.c | 63 +++++++++++++++++++ .../wireless/realtek/rtlwifi/rtl8192du/fw.h | 9 +++ .../wireless/realtek/rtlwifi/rtl8192du/led.c | 10 +++ .../wireless/realtek/rtlwifi/rtl8192du/led.h | 9 +++ 4 files changed, 91 insertions(+) create mode 100644 drivers/net/wireless/realtek/rtlwifi/rtl8192du/fw.c create mode 100644 drivers/net/wireless/realtek/rtlwifi/rtl8192du/fw.h create mode 100644 drivers/net/wireless/realtek/rtlwifi/rtl8192du/led.c create mode 100644 drivers/net/wireless/realtek/rtlwifi/rtl8192du/led.h
