From 9a80e714350a959caadfd6e2405cd1f7e8ea86d3 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sun, 3 Apr 2016 09:18:53 +0200 Subject: [PATCH] usb: kbd: Do not deregister usbkbd twice when using dm The dm usb_kbd_remove function() will deregister the usb keyboard for us on a "usb reset" / "usb stop" so there is no need to manually call usb_kbd_deregister() in the dm case. This commit removes usb_kbd_deregister() in the dm case fixing the following "usb reset" errors: usb_kbd_remove: warning, ret=-6 device_remove: Device 'usb_kbd' failed to remove, but children are gone Signed-off-by: Hans de Goede --- cmd/usb.c | 2 +- common/usb_kbd.c | 3 ++- 2 files changed, 3 insertions(+), 2 deletions(-) diff --git a/cmd/usb.c b/cmd/usb.c index 9ed5dc61ea..97dd6f0099 100644 --- a/cmd/usb.c +++ b/cmd/usb.c @@ -541,7 +541,7 @@ static int do_usbboot(cmd_tbl_t *cmdtp, int flag, int argc, char * const argv[]) static int do_usb_stop_keyboard(int force) { -#ifdef CONFIG_USB_KEYBOARD +#if !defined CONFIG_DM_USB && defined CONFIG_USB_KEYBOARD if (usb_kbd_deregister(force) != 0) { printf("USB not stopped: usbkbd still using USB\n"); return 1; diff --git a/common/usb_kbd.c b/common/usb_kbd.c index d84865fbbe..97f79f8eb8 100644 --- a/common/usb_kbd.c +++ b/common/usb_kbd.c @@ -566,7 +566,6 @@ int drv_usb_kbd_init(void) /* No USB Keyboard found */ return -1; } -#endif /* Deregister the keyboard. */ int usb_kbd_deregister(int force) @@ -599,6 +598,8 @@ int usb_kbd_deregister(int force) #endif } +#endif + #ifdef CONFIG_DM_USB static int usb_kbd_probe(struct udevice *dev) -- 2.39.5
