[PATCH 6.19 219/311] iio: adc: ade9000: move mutex init before IRQ registration

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Antoniu Miclaus <antoniu.miclaus@analog.com>

commit 0206dd36418c104c0b3dea4ed7047e21eccb30b0 upstream.

Move devm_mutex_init() before ade9000_request_irq() calls so that
st->lock is initialized before any handler that depends on it can run.

Fixes: 81de7b4619fc ("iio: adc: add ade9000 support")
