[PATCH] i2c: i2c-omap: Fix BUFSTAT_REG reading

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Eero Nurkkala <ext-eero.nurkkala@xxxxxxxxx>

The amount of bytes to receive is read from wrong
place. It is the 6 bits starting from the bit 8 from
BUFSTAT_REG that indicate this amount. Not the 8 LSB:s.
6 LSB:s are used for the TX buffer.
