usb: core: reduce power-on-good delay time of root hub

2021-06-03T06:22:09Z

commit 90d28fb53d4a51299ff324dede015d5cb11b88a2 upstream. Return the exactly delay time given by root hub descriptor, this helps to reduce resume time etc. Due to the root hub descriptor is usually provided by the host controller driver, if there is compatibility for a root hub, we can fix it easily without affect other root hub Acked-by: Alan Stern Signed-off-by: Chunfeng Yun Link: https://lore.kernel.org/r/1618017645-12259-1-git-send-email-chunfeng.yun@mediatek.com Signed-off-by: Greg Kroah-Hartman

scsi: libsas: Use _safe() loop in sas_resume_port()

2021-06-03T06:22:08Z

[ Upstream commit 8c7e7b8486cda21269d393245883c5e4737d5ee7 ] If sas_notify_lldd_dev_found() fails then this code calls: sas_unregister_dev(port, dev); which removes "dev", our list iterator, from the list. This could lead to an endless loop. We need to use list_for_each_entry_safe().

scsi: BusLogic: Fix 64-bit system enumeration error for Buslogic

2021-06-03T06:22:08Z

[ Upstream commit 56f396146af278135c0ff958c79b5ee1bd22453d ] Commit 391e2f25601e ("[SCSI] BusLogic: Port driver to 64-bit") introduced a serious issue for 64-bit systems. With this commit, 64-bit kernel will enumerate 8*15 non-existing disks. This is caused by the broken CCB structure. The change from u32 data to void *data increased CCB length on 64-bit system, which introduced an extra 4 byte offset of the CDB. This leads to incorrect response to INQUIRY commands during enumeration. Fix disk enumeration failure by reverting the portion of the commit above which switched the data pointer from u32 to void.

libertas: register sysfs groups properly

2021-06-03T06:22:08Z

[ Upstream commit 7e79b38fe9a403b065ac5915465f620a8fb3de84 ] The libertas driver was trying to register sysfs groups "by hand" which causes them to be created _after_ the device is initialized and announced to userspace, which causes races and can prevent userspace tools from seeing the sysfs files correctly. Fix this up by using the built-in sysfs_groups pointers in struct net_device which were created for this very reason, fixing the race condition, and properly allowing for any error that might have occured to be handled properly.
