Subject: i2c-ibm_iic: Add support for new-style clients
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7589a326d1d8c9da575ca4cbc6a3e6af02b57ead;p=openwrt%2Fstaging%2Fblogic.git

i2c-ibm_iic: Add support for new-style clients

Use i2c_bit_add_numbered_adapter() if device id specified, so that the
i2c-ibm_iic adapter works well with new-style pre-declared devices.
