Subject: bq27xxx: what is going on with MSLEEP() macro

Hi!

0670c9b35 drivers/power/supply/bq27xxx_battery.c #define BQ27XXX_MSLEEP(i) usleep_range((i)*1000, (i)*1000+500)

Liam, is this really neccessary? Defining MSLEEP to be USLEEP_RANGE is
quite sneaky and confusing. Plus I don't believe we should be
usleep-ing for 25msec. Can we just replace it with regular msleep?

0670c9b35 drivers/power/supply/bq27xxx_battery.c         /* DO NOT read BQ27XXX_DM_CKSUM
here to verify it! That may cause NVM

Normal kernel style for multi-line comments is

/*
 * foo
 */

Can you fix those?

Thanks,
									Pavel
