Subject: [PATCH v1 0/2] i2c: Stop i2c modules being unloaded while in use.

From: Jim Baxter <jim_baxter@...tor.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
