that the interrupt we're given is rising edge (and things won't work if

low, and level high interrupts.
Empirically, on my system, switching to level interrupts has fixed a
problem I had with significant (~40%) interrupt loss with edge
interrupts. This issue is likely related to the SoC I'm using (Allwinner
H3), but being able to switch the interrupt type is still a very useful
workaround.
I tested this with each interrupt type and verified correct behavior in
a logic analyzer.
Add support for these interrupt types while also eliminating the error

uapi: remove telephony headers
ixjuser.h includes the telephony.h header. Other than that no kernel
code uses any of these headers. The last user of the ixjuser.h header
has been removed in commit 7326446c728 (Staging: remove telephony
