[Bug 2063497] Re: MIPI camera on Lenovo Carbon X1 will not work

I moved the driver file up a directory from /lib/firmware/intel/ipu to
/lib/firmware/intel and now the firmware appears to be loaded. But
something else is still wrong here:

Title:
MIPI camera on Lenovo Carbon X1 will not work

Status in linux package in Ubuntu:
New

Bug description:
I followed the suggestions here for handling the Intel MIPI camera
replacing 22.04 for 24.04: https://wiki.ubuntu.com/Lenovo

Perhaps I should have installed 22.04? Anyway, this is a new laptop
so I went with the new release.

I tried both the generic and oem kernel. Same. The pertinent message
seems to be:

[ 18.420012] intel-ipu6 0000:00:05.0: Direct firmware load for intel/ipu6ep_fw.bin failed with error -2
[ 18.420017] intel-ipu6 0000:00:05.0: Requesting signed firmware failed
[ 18.420023] intel-ipu6: probe of 0000:00:05.0 failed with error -2
