ff949d981c775332be94be70397ee1df20bc68e5 | Analyze and fix the following issue in the Linux kernel code: spi: spi-fsl-lpspi: Fix off-by-one in prescale max | Problem Details:
The commit 783bf5d09f86 ("spi: spi-fsl-lpspi: limit PRESCALE bit in
TCR register") doesn't implement the prescaler maximum as intended.
The maximum allowed value for i.MX93 should be 1 and for i.MX7ULP
it should be 7. So this needs also a adjustment of the comparison
in the scldiv calculation.

scx_ops_disable_workfn() only switches !TASK_DEAD tasks out of SCX while
calling scx_ops_exit_task() on all tasks including dead ones. This can leave
a dead task on SCX but with SCX_TASK_NONE state, which is inconsistent.

Fix two inconsistencies in feature names as discussed in [1]:
1. Rename "dwarf-unwind-support" to "dwarf-unwind"
