RE: [PATCHv2] i2c: i2c-imx: Fix format warning for dev_dbg

[Li.Xiubo@xxxxxxxxxxxxx]

Hi Jingoo,

Thanks for your advice.

This patch is mainly resolving the warning issue. And some
thing like : 'i2c: i2c-imx: Fix format warning for dev_db'
Could be more obvious.

I think adding 'printf extension %pR for struct resource'
to the commit comment will better.

BRs
