Subject: patch "iio: imu: inv_icm42600: Drop redundant pm_runtime reinitialization in" added to char-misc-next
Date: Tue, 23 Sep 2025 14:19:20 +0200	[thread overview]
Message-ID: <2025092320-glade-thirteen-18ad@gregkh> (raw)


This is a note to let you know that I've just added the patch titled

    iio: imu: inv_icm42600: Drop redundant pm_runtime reinitialization in

to my char-misc git tree which can be found at
    git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git
in the char-misc-next branch.

The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)

The patch will also be merged in the next major kernel release
during the merge window.

If you have any questions about this process, please let me know.

Subject: iio: imu: inv_icm42600: Drop redundant pm_runtime reinitialization in
 resume

Remove unnecessary calls to pm_runtime_disable(), pm_runtime_set_active(),
and pm_runtime_enable() from the resume path. These operations are not
required here and can interfere with proper pm_runtime state handling,
especially when resuming from a pm_runtime suspended state.
