Revision 6c782a5ea56a799658e213a78dc1455264938afa authored by Michail Georgios Etairidis on 20 June 2017, 08:20:42 UTC, committed by Wolfram Sang on 22 June 2017, 08:52:02 UTC
The i2c-imx driver incorrectly uses readb()/writeb() to read and
write to the appropriate registers when performing a repeated start.
The appropriate imx_i2c_read_reg()/imx_i2c_write_reg() functions
should be used instead. Performing a repeated start results in
a kernel panic. The platform is imx.
