Subject: [PATCH v1 0/2] i2c: Stop i2c modules being unloaded while in use.
Date: Wed, 7 Sep 2016 21:05:27 +0100 [thread overview]
Message-ID: <1473278729-16329-1-git-send-email-jim_baxter@mentor.com> (raw)
From: Jim Baxter <jim_baxter@mentor.com>
This patchset adds a new i2c_mux_add_reparented_adapter API to the i2c
that allows owning modules to use module_get/module_put and stop the
i2c bus module being removed whilst in use.
This was tested on an ARM i.MX6 Sabre board with the pca953x gpio module.
Joshua Frkuska (2):
i2c-mux: add i2c_mux_add_reparented_adapter api
i2c-mux-gpio: call i2c_add_reparented_mux_adapter
