Many changes were done in drivers/pinctrl/bcm/pinctrl-bcm2835.c between
5.4.171 and 5.4.179.
The following 3 patches do not apply any more:
* target/linux/bcm27xx/patches-5.4/950-0316-pinctrl-bcm2835-Add-support-for-BCM2711-pull-up-func.patch
This was already integrated in kernel v5.4-rc1, it was never needed.
* target/linux/bcm27xx/patches-5.4/950-0328-Revert-pinctrl-bcm2835-Pass-irqchip-when-adding-gpio.patch
* target/linux/bcm27xx/patches-5.4/950-0362-pinctrl-bcm2835-Change-init-order-for-gpio-hogs.patch
I think these were done to fix the problem which was really fixed in
commit 75278f1aff5e ("pinctrl: bcm2835: Change init order for gpio
hogs") from v5.4.175
target/linux/generic/backport-5.4/716-v5.5-net-sfp-move-fwnode-parsing-into-sfp-bus-layer.patch
Move fwnode_device_is_available to the same position as in kernel 5.10.
target/linux/layerscape/patches-5.4/302-dts-0083-arm64-ls1028a-qds-correct-bus-of-rtc.patch
Applied in commit 65816c1034769e714edb70f59a33bc5472d9e55f ("arm64: dts:
ls1028a-qds: move rtc node to the correct i2c bus")
Compile-tested: lantiq/xrx200, bcm27xx/bcm2710
Run-tested: lantiq/xrx200

Subject: [PATCH] clk-bcm2835: Avoid null pointer exception
|
|
|
|
clk_desc_array[BCM2835_PLLB] doesn't exist so we dereference null when iterating
