From 6254312352dfd1c996245cb3bc74be901dc165cc Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Wed, 22 Mar 2006 03:48:33 -0300 Subject: [PATCH] V4L/DVB (3568a): saa7114: Fix i2c block write Fix the i2c block write mode of the saa7114 driver. A previous code change accidentally commented out a local variable increment, which should have been kept, causing the register writes over the I2C bus to never be batched, replacing any attempted block write by slower, individual write transactions. Also drop the commented out code, as it only adds to confusion.
