Subject: [PATCH 0/2] clk: kunit: Fix the lockdep warnings

Hi,

Here's a small series to address the lockdep warning we have when
running the clk kunit tests with lockdep enabled.

For the record, it can be tested with:

$ ./tools/testing/kunit/kunit.py run \
    --kunitconfig=drivers/clk \
    --cross_compile aarch64-linux-gnu- --arch arm64 \
    --kconfig_add CONFIG_DEBUG_KERNEL=y \
    --kconfig_add CONFIG_PROVE_LOCKING=y

Let me know what you think,
Maxime
