    "summary": "In the Linux kernel, the following vulnerability has been resolved: clk: spacemit: mark K1 pll1_d8 as critical The pll1_d8 clock is enabled by the boot loader, and is ultimately a parent for numerous clocks, including those used by APB and AXI buses. Guodong Xu discovered that this clock got disabled while responding to getting -EPROBE_DEFER when requesting a reset controller. The needed clock (CLK_DMA, along with its parents) had already been enabled. To respond to the probe deferral return, the CLK_DMA clock was disabled, and this led to parent clocks also reducing their enable count. When the enable count for pll1_d8 was decremented it became 0, which caused it to be disabled. This led to a system hang. Marking that clock critical resolves this by preventing it from being disabled. Define a new macro CCU_FACTOR_GATE_DEFINE() to allow clock flags to be supplied for a CCU_FACTOR_GATE clock.",
