[PATCH 5.15.y] drm/amd/display: Fix out-of-bounds access in 'dcn21_link_encoder_create'

by bin.lan.cn＠windriver.com

From: Srinivasan Shanmugam <srinivasan.shanmugam(a)amd.com> [ Upstream commit 63de35a8fcfca59ae8750d469a7eb220c7557baf ] An issue was identified in the dcn21_link_encoder_create function where an out-of-bounds access could occur when the hpd_source index was used to reference the link_enc_hpd_regs array. This array has a fixed size and the index was not being checked against the array's bounds before accessing it. This fix adds a conditional check to ensure that the hpd_source index is within the valid range of the link_enc_hpd_regs array. If the index is out of bounds, the function now returns NULL to prevent undefined behavior.

[PATCH 5/5] xhci: Limit time spent with xHC interrupts disabled during bus resume

by Mathias Nyman

Current xhci bus resume implementation prevents xHC host from generating interrupts during high-speed USB 2 and super-speed USB 3 bus resume. Only reason to disable interrupts during bus resume would be to prevent the interrupt handler from interfering with the resume process of USB 2 ports. Host initiated resume of USB 2 ports is done in two stages. The xhci driver first transitions the port from 'U3' to 'Resume' state, then wait in Resume for 20ms, and finally moves port to U0 state. xhci driver can't prevent interrupts by keeping the xhci spinlock due to this 20ms sleep. Limit interrupt disabling to the USB 2 port resume case only. resuming USB 2 ports in bus resume is only done in special cases where USB 2 ports had to be forced to suspend during bus suspend. The current way of preventing interrupts by clearing the 'Interrupt Enable' (INTE) bit in USBCMD register won't prevent the Interrupter registers 'Interrupt Pending' (IP), 'Event Handler Busy' (EHB) and USBSTS register Event Interrupt (EINT) bits from being set. New interrupts can't be issued before those bits are properly clered. Disable interrupts by clearing the interrupter register 'Interrupt Enable' (IE) bit instead. This way IP, EHB and INTE won't be set before IE is enabled again and a new interrupt is triggered.
