Marek Szyprowski 2c46871ac4 i2c: s3c24xx: fix transferring more than one message in polling mode ... [ Upstream commit 990489e1042c6c5d6bccf56deca68f8dbeed8180 ] To properly handle ACK on the bus when transferring more than one message in polling mode, move the polling handling loop from s3c24xx_i2c_message_start() to s3c24xx_i2c_doxfer(). This way i2c_s3c_irq_nextbyte() is always executed till the end, properly acknowledging the IRQ bits and no recursive calls to i2c_s3c_irq_nextbyte() are made. While touching this, also fix finishing transfers in polling mode by using common code path and always waiting for the bus to become idle and disabled.
