[PATCH 2/2] thermal/drivers/qcom/tsens: Drop __init from the per-SoC ->init callbacks

[Christian Schmidbauer]

init_8226(), init_8909(), init_8939(), init_8952(), init_8956(),
init_9607(), init_tsens_v1_no_rpm() and init_tsens_v2_no_rpm() are
marked __init, but tsens_probe() calls them through priv->ops->init()
and can run after free_initmem().  The call then jumps into memory that
is no longer mapped executable, and the kernel oopses.

The probe runs that late when fw_devlink defers it until the deferred
probe timeout.

Fixes: a7d3006be5ca ("thermal/drivers/tsens: Sort out msm8976 vs msm8956 data")
