While the atomisp driver might be used for Surface 3 and Surface Pro 3
cameras in the future, it currently resides in staging and doesn't seem
to work (at least according to its TODO file). It furthermore causes
a notice to be printed, warning about the use of trace_printk(). So
disable it for now to shut up that warning.
Currently, the kernel emits a notice at boot, warning about the usage of
trace_printk(). Disabling samples in efaa3edaaa ("Do not build samples
for Debian/Ubuntu") apparently wasn't enough to get rid of that. So
disable more sample and testing stuff that might call this function.
The Debian LTS kernel does not have CONFIG_ACPI_I2C_OPREGION set. This
is likely due to its dependency on CONFIG_I2C=y. Thus explicitly set
those two options.
This commit reverts upstream commit
9945722afdc3443eab826b2da1122509a13a50a5 (builddeb: make headers package thinner)
which drops some files from the linux-headers package. These files seem
to be required by some out-of-tree modules (see #170).
