From: Uwe Kleine-König Date: Mon, 16 Jul 2012 13:40:17 +0000 (+0200) Subject: mfd: Drop modifying mc13xxx driver's id_table in probe X-Git-Tag: upstream/snapshot3+hdmi~6919^2~19 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8b8495532c6ba85221b0f9757e1581b52ed66c9a;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git mfd: Drop modifying mc13xxx driver's id_table in probe This was introduced in commit 876989d (mfd: Add device tree probe support for mc13xxx) for spi and later while introducing support for i2c copied to the i2c driver. Modifying driver details is very strange, for example probing an mc13892 device (instantiated via dt) removes the driver's ability to handle (traditionally probed) mc13783 devices in this case. I'm not aware of any problems that make this hack necessary and if there were some, they'd have to be fixed in the spi/i2c core, not in a driver.
