Hi Greg,
Today's linux-next merge of the usb tree got a conflict in:
drivers/usb/misc/ucsi.c
between commit:
94116f8126de ("ACPI: Switch to use generic guid_t in acpi_evaluate_dsm()")
from the uuid tree and commit:
8243edf44152 ("usb: typec: ucsi: Add ACPI driver")
from the usb tree.
I fixed it up (the latter deleted the file, so I did that - I think the
new code is ok with then new guid handling) and can carry the fix as
necessary. This is now fixed as far as linux-next is concerned, but any
non trivial conflicts should be mentioned to your upstream maintainer
when your tree is submitted for merging. You may also want to consider
cooperating with the maintainer of the conflicting tree to minimise any
particularly complex conflicts.
Almost right :-(
I got the following error:
drivers/usb/typec/ucsi/ucsi_acpi.c: In function 'ucsi_acpi_dsm':
drivers/usb/typec/ucsi/ucsi_acpi.c:33:48: error: passing argument 2 of 'acpi_evaluate_dsm' from incompatible pointer type [-Werror=incompatible-pointer-types]

I have applied the following merge fix patch (the first hunk is
probably not strictly necessary):
