Some UAPI headers included <stdlib.h>, like this:
#ifndef __KERNEL__
#include <stdlib.h>
#endif
As it turned out, they just included it for no good reason.
After some fixes, now I can compile-test UAPI headers
(CONFIG_UAPI_HEADER_TEST=y) without including <stdlib.h> from the
system header search paths.
To avoid somebody getting it back again, this commit adds the dummy
header, usr/dummy-include/stdlib.h
I added $(srctree)/usr/dummy-include to the header search paths.
Because it is searched before the system directories, if someone
tries to include <stdlib.h>, they will see the error message.
While I am here, I also replaced $(objtree)/usr/include with $(obj),
but it has no functional change.
If we can make kernel headers self-contained (that is, none of exported
kernel headers includes system headers), we will be able to add the
-nostdinc flag, but that is much far from where we stand now.
As a realistic solution, we can ban header inclusion individually by
putting a dummy header into usr/dummy-include/.
Currently, no header include <stdbool.h>. I put it as well before somebody
attempts to use it.

SM5703 is another MFD from Silicon Mitus which has a very similar MUIC
unit to the one in SM5502. The only difference I've noticed is slightly different
configuration only enables the interrupts which are exactly the same as on SM5502.
If we make use of different interrupts in the future, this can be improved by having
a separate struct for SM5703, but the main functionality (detecting cable or OTG adapter)
is working properly.

The extcon_get_extcon_dev() function returns error pointers on error,
NULL when it's a -EPROBE_DEFER defer situation, and ERR_PTR(-ENODEV)
when the CONFIG_EXTCON option is disabled. This is very complicated for
the callers to handle and a number of them had bugs that would lead to
an Oops.
In real life, there are two things which prevented crashes. First,
error pointers would only be returned if there was bug in the caller
where they passed a NULL "extcon_name" and none of them do that.
Second, only two out of the eight drivers will build when CONFIG_EXTCON
is disabled.
The normal way to write this would be to return -EPROBE_DEFER directly
when appropriate and return NULL when CONFIG_EXTCON is disabled. Then
the error handling is simple and just looks like:
dev->edev = extcon_get_extcon_dev(acpi_dev_name(adev));
if (IS_ERR(dev->edev))
return PTR_ERR(dev->edev);
For the two drivers which can build with CONFIG_EXTCON disabled, then
extcon_get_extcon_dev() will now return NULL which is not treated as an
error and the probe will continue successfully. Those two drivers are
"typec_fusb302" and "max8997-battery". In the original code, the
typec_fusb302 driver had an 800ms hang in tcpm_get_current_limit() but
now that function is a no-op. For the max8997-battery driver everything
should continue working as is.
