Subject: i2c: i801: use i2c_mark_adapter_suspended/resumed
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d0d0f827e067b70c533cca98df772fc65729b522;p=linux.git

i2c: i801: use i2c_mark_adapter_suspended/resumed

When entering the suspend callback, at first we should ensure that
transfers are finished and I2C core can't start further transfers.
Use i2c_mark_adapter_suspended() for this purpose, and complement it
with a call to i2c_mark_adapter_resumed() in the resume path.
