Uwe Kleine-König fe20b1dcd2 power: supply: Switch i2c drivers back to use .probe()
After commit b8a1a4cd5a ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

ye xingchen 35aa06286c power: supply: use sysfs_emit() instead of scnprintf() for sysfs show()
As documented in Documentation/filesystems/sysfs.rst the sysfs
show() function should use sysfs_emit() or sysfs_emit_at() to
format the userspace return value. This replaces all instances
of scnprintf() with sysfs_emit() in the power-supply subsystem.

Uwe Kleine-König 924668b4ed power: supply: bq24257: Convert to i2c's .probe_new()
.probe_new() doesn't get the i2c_device_id * parameter, so determine
that explicitly in the probe function.

Uwe Kleine-König ed5c2f5fd1 i2c: Make remove callback return void
The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

Alexander A. Klimov 81bd45fc36 power: supply: bq2xxxx: Replace HTTP links with HTTPS ones
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.
