CC [M] /var/lib/dkms/ddcci/0.4.1/build/ddcci/ddcci.o
/var/lib/dkms/ddcci/0.4.1/build/ddcci/ddcci.c:1295:27: error: initialization of ‘void (*)(struct device *)’ from incompatible pointer type ‘int (*)(struct device *)’ [-Werror=incompatible-pointer-types]
1295 | .remove = ddcci_device_remove
| ^~~~~~~~~~~~~~~~~~~ |
[Impact]
ddcci dkms is failing to build with the latest 5.15 kernel on jammy:
CC [M] /var/lib/dkms/ddcci/0.4.1/build/ddcci/ddcci.o
/var/lib/dkms/ddcci/0.4.1/build/ddcci/ddcci.c:1295:27: error: initialization of ‘void (*)(struct device *)’ from incompatible pointer type ‘int (*)(struct device *)’ [-Werror=incompatible-pointer-types]
1295 | .remove = ddcci_device_remove
| ^~~~~~~~~~~~~~~~~~~
[Test case]
sudo apt install ddcci-dkms
[Fix]
The signature of struct bus_type.remove changed to a void function, we just need to adjust the handler with kernels >= 5.15.
[Regression potential]
We may have ddcci-dkms regressions with old kernels if the patch is not doing the right thing, but the change is really minimal, so the risk of regressions is very low. |
