This file has a HUGE debugging sysfs file that spews out a lot of information all at once, which violates the one-value-per-file rule for sysfs. If this is really needed, it should go into debugfs, but given the age of this driver, I strongly doubt anyone is using it anymore. So just remove the file entirely, it was never documented, so obviously, no one actually needed it :) Cc: Felipe Balbi <balbi@xxxxxxxxxx> Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- drivers/usb/phy/phy-fsl-usb.c | 93 ----------------------------------- 1 file changed, 93 deletions(-) diff --git a/drivers/usb/phy/phy-fsl-usb.c b/drivers/usb/phy/phy-fsl-usb.c index b451f4695f3f..93d2257aeec8 100644 --- a/drivers/usb/phy/phy-fsl-usb.c +++ b/drivers/usb/phy/phy-fsl-usb.c @@ -957,98 +957,6 @@ int usb_otg_start(struct platform_device *pdev) return 0; } -/* - * state file in sysfs - */ -static ssize_t show_fsl_usb2_otg_state(struct device *dev, - struct device_attribute *attr, char *buf) -{ - struct otg_fsm *fsm = &fsl_otg_dev->fsm; - char *next = buf; - unsigned size = PAGE_SIZE; - int t; - - mutex_lock(&fsm->lock); - - /* basic driver infomation */ - t = scnprintf(next, size, - DRIVER_DESC "\n" "fsl_usb2_otg version: %s\n\n", - DRIVER_VERSION); - size -= t; - next += t; - - /* Registers */ - t = scnprintf(next, size, - "OTGSC: 0x%08x\n" - "PORTSC: 0x%08x\n" - "USBMODE: 0x%08x\n" - "USBCMD: 0x%08x\n" - "USBSTS: 0x%08x\n" - "USBINTR: 0x%08x\n", - fsl_readl(&usb_dr_regs->otgsc), - fsl_readl(&usb_dr_regs->portsc), - fsl_readl(&usb_dr_regs->usbmode), - fsl_readl(&usb_dr_regs->usbcmd), - fsl_readl(&usb_dr_regs->usbsts), - fsl_readl(&usb_dr_regs->usbintr)); - size -= t; - next += t; - - /* State */ - t = scnprintf(next, size, - "OTG state: %s\n\n", - usb_otg_state_string(fsl_otg_dev->phy.otg->state)); - size -= t; - next += t; - - /* State Machine Variables */ - t = scnprintf(next, size, - "a_bus_req: %d\n" - "b_bus_req: %d\n" - "a_bus_resume: %d\n" - "a_bus_suspend: %d\n" - "a_conn: %d\n" - "a_sess_vld: %d\n" - "a_srp_det: %d\n" - "a_vbus_vld: %d\n" - "b_bus_resume: %d\n" - "b_bus_suspend: %d\n" - "b_conn: %d\n" - "b_se0_srp: %d\n" - "b_ssend_srp: %d\n" - "b_sess_vld: %d\n" - "id: %d\n", - fsm->a_bus_req, - fsm->b_bus_req, - fsm->a_bus_resume, - fsm->a_bus_suspend, - fsm->a_conn, - fsm->a_sess_vld, - fsm->a_srp_det, - fsm->a_vbus_vld, - fsm->b_bus_resume, - fsm->b_bus_suspend, - fsm->b_conn, - fsm->b_se0_srp, - fsm->b_ssend_srp, - fsm->b_sess_vld, - fsm->id); - size -= t; - next += t; - - mutex_unlock(&fsm->lock); - - return PAGE_SIZE - size; -} - -static DEVICE_ATTR(fsl_usb2_otg_state, S_IRUGO, show_fsl_usb2_otg_state, NULL); - -static struct attribute *fsl_otg_attrs[] = { - &dev_attr_fsl_usb2_otg_state.attr, - NULL, -}; -ATTRIBUTE_GROUPS(fsl_otg); - /* Char driver interface to control some OTG input */ /* @@ -1167,7 +1075,6 @@ struct platform_driver fsl_otg_driver = { .driver = { .name = driver_name, .owner = THIS_MODULE, - .dev_groups = fsl_otg_groups, }, }; -- 2.27.0
