Subject: How to build I2C_MUX in media_build as rtl28xxu depends on it ?
Date: Mon, 24 Mar 2014 19:08:50 +0100 [thread overview]
Message-ID: <533074B2.4000007@hoogenraad.net> (raw)
In-Reply-To: <1394756071-22410-12-git-send-email-crope@iki.fi>
After recent changes, I cannot build rtl28xxu on systems with linux
2.6.32 or 3.2.0.
rtl28xxu is one of the few drivers depending on I2C_MUX.
Kconfig.kern lists I2C_MUX (correctly) as not in the kernel of the system.
I don't know if it is possible to load a new module for that.
Who can help me with this ?
