Remove this and dump the efuse from a single place using a new function rtl8xxxu_dump_efuse(). Also, use print_hex_dump() to print the efuse instead of a loop and dev_info(). It shows the ASCII interpretation of the bytes, which is nice. Signed-off-by: Bitterblue Smith --- v3: - Implement suggestion from Ping-Ke Shih: - Use EFUSE_MAP_LEN instead of EFUSE_REAL_CONTENT_LEN_8723A. They have the same value. v2: - Patch is new in v2. --- .../net/wireless/realtek/rtl8xxxu/rtl8xxxu_8188f.c | 11 ----------- .../net/wireless/realtek/rtl8xxxu/rtl8xxxu_8192c.c | 10 ---------- .../net/wireless/realtek/rtl8xxxu/rtl8xxxu_8192e.c | 9 --------- .../net/wireless/realtek/rtl8xxxu/rtl8xxxu_8723b.c | 11 ----------- .../net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.c | 13 +++++++++++++ 5 files changed, 13 insertions(+), 41 deletions(-) diff --git a/drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_8188f.c b/drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_8188f.c index 2c4f403ba68f..ba28a4c00d3b 100644 --- a/drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_8188f.c +++ b/drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_8188f.c @@ -716,7 +716,6 @@ static void rtl8188fu_init_statistics(struct rtl8xxxu_priv *priv) static int rtl8188fu_parse_efuse(struct rtl8xxxu_priv *priv) { struct rtl8188fu_efuse *efuse = &priv->efuse_wifi.efuse8188fu;
