[PATCH V3 1/8] clk: qcom: clk-alpha-pll: Fix CAL_L_VAL override for LUCID EVO PLL

by Ajit Pandey

In LUCID EVO PLL CAL_L_VAL and L_VAL bitfields are part of single PLL_L_VAL register. Update for L_VAL bitfield values in PLL_L_VAL register using regmap_write() API in __alpha_pll_trion_set_rate callback will override LUCID EVO PLL initial configuration related to PLL_CAL_L_VAL bit fields in PLL_L_VAL register. Observed random PLL lock failures during PLL enable due to such override in PLL calibration value. Use regmap_update_bits() with L_VAL bitfield mask instead of regmap_write() API to update only PLL_L_VAL bitfields in __alpha_pll_trion_set_rate callback.

[PATCH v2 2/2] xhci: Apply broken streams quirk to Etron EJ188 xHCI host

[PATCH 0/2] cpufreq: qcom-nvmem: fix memory leaks and add auto device node cleanup

by Javier Carrasco

There are a number of error paths in the probe function that do not call of_node_put() to decrement the np device node refcount, leading to memory leaks if those errors occur. In order to ease backporting, the fix has been divided into two patches: the first one simply adds the missing calls to of_node_put(), and the second one adds the __free() macro to the existing device nodes to remove the need for of_node_put(), ensuring that the same bug will not arise in the future. The issue was found by chance while analyzing the code, and I do not have the hardware to test it beyond compiling and static analysis tools. Although the issue is clear and the fix too, if someone wants to volunteer to test the series with real hardware, it would be great.
