Clock stretching is not supposed to last long, so asking to be rescheduled while waiting for the clock line to be released by a slave makes little sense. Odds are that the clock line will long have been released when we run again, so we will have lost time and may even get an SMBus timeout because of this. So just busy-wait in that case. This also participates in the effort to make i2c-algo-bit usable in contexts that can't sleep. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Ben Skeggs <bskeggs@redhat.com> |
