Subject: [PATCH] Staging: iio: meter: Use devm functions
Date: Sun, 4 Oct 2015 10:04:32 +0530 [thread overview]
Message-ID: <1443933272-23398-1-git-send-email-shraddha.6596@gmail.com> (raw)
Introduce use of managed resource function devm_iio_trigger_alloc
instead of iio_trigger_alloc and devm_request_irq instead of request_irq
Remove corresponding calls to iio_trigger_free and free_irq in the probe
and remove functions.
The now unnecessary labels error_free_trig and err_free_irq are dropped.
