[PATCH AUTOSEL 5.10 02/15] pinctrl: aspeed: Fix potential NULL dereference in aspeed_pinmux_set_mux()

[Sasha Levin]

From: Haowen Bai <baihaowen@meizu.com>

[ Upstream commit 84a85d3fef2e75b1fe9fc2af6f5267122555a1ed ]

pdesc could be null but still dereference pdesc->name and it will lead to
a null pointer access. So we move a null check before dereference.

[PATCH AUTOSEL 5.10 12/15] ARM: dts: stm32: use the correct clock source for CEC on stm32mp151

[Sasha Levin]

From: Gabriel Fernandez <gabriel.fernandez@foss.st.com>

[ Upstream commit 78ece8cce1ba0c3f3e5a7c6c1b914b3794f04c44 ]

The peripheral clock of CEC is not LSE but CEC.

[PATCH AUTOSEL 5.10 13/15] Revert "can: xilinx_can: Limit CANFD brp to 2"

[Sasha Levin]

From: Srinivas Neeli <srinivas.neeli@xilinx.com>

[ Upstream commit c6da4590fe819dfe28a4f8037a8dc1e056542fb4 ]

This reverts commit 05ca14fdb6fe65614e0652d03e44b02748d25af7.

On early silicon engineering samples observed bit shrinking issue when
we use brp as 1. Hence updated brp_min as 2. As in production silicon
this issue is fixed, so reverting the patch.
