[RFC PATCH] mn88472: reduce firmware download chunk size

2015-02-19 Thread Antti Seppälä
It seems that currently the firmware download on the mn88472 is somehow wrong for my Astrometa HD-901T2. Reducing the download chunk size (mn88472_config.i2c_wr_max) to 2 makes the firmware download consistently succeed. Any larger value causes the download to always fail: [7.671482]
