Subject: [PATCH] cocci: Find i2c drivers with an of_device table that isn't exported
Date: Tue, 10 May 2016 15:39:25 +0100	[thread overview]
Message-ID: <1462891165-25013-1-git-send-email-kieran@bingham.xyz> (raw)
In-Reply-To: <8df98822-22d4-7d03-2b84-6e96e0b6f8af@osg.samsung.com>

This script will then add the MODULE_DEVICE_TABLE(of, ...) to correctly export
the device tree table

Usage: spatch --sp-file scripts/coccinelle/i2c/i2c_table_missing_export.cocci . --in-place
---

Javier,

I've been working on scripts to automate some of the conversion processes
involved in this DT_I2C project.

This one adds missing exports for i2c device tables.

Feel free to use it if it helps.

I have another one which searches for drivers which have both an I2C device table, and an OF device table,
and a probe function which does not use the second parameter.

It then performs the conversion to the probe_new() and removes the I2C device table.

Should help with the bulk of the conversion
