Title:
Build failure as invalid use of return in arch-has-odm-enabled.sh
removes AAEON modules
Status in linux-hwe-5.11 package in Ubuntu:
New
Bug description:
[Steps to reproduce from scratch]
1. Download ubuntu-20.04.3-desktop-amd64.iso, install it on some
machine, restart to login to the newly installed Ubuntu, and open
GNOME Terminal to type the following commands to bring the system up-
to-date:
sudo apt-get update
sudo apt-get -y dist-upgrade
2. Restart, login to the updated Ubuntu, and open GNOME Terminal to
type the following commands to prepare linux-hwe-5.11 build:
sudo apt-get install -y --install-suggests build-essential
sudo apt-get build-dep -y linux-image-unsigned-`uname -r`
mkdir ~/workspace
cd ~/workspace
apt-get source linux-image-unsigned-`uname -r`
3. Type the following command to make /bin/sh to point to bash:
sudo ln -sf bash /bin/sh
4. Type the following command to build linux-hwe-5.11 and reproduce
the error:
cd ~/workspace/linux-hwe-5.11-5.11.0
time dpkg-buildpackage --no-sign -us -ui -uc --unsigned-changes
[The failure]
Step 4 terminates with the following error message, quoting:
Debug: module-check-generic

End quote.
[The error]
The executable shell script ~/workspace/linux-
hwe-5.11-5.11.0/debian/scripts/misc/arch-has-odm-enabled.sh, which is
executed during the syncconfig phase as directed by the file
~/workspace/linux-hwe-5.11-5.11.0/ubuntu/Kconfig, uses the builtin
`return' outside a shell function. While `dash' ignores the incorrect
usage, `bash' errors out immediately with the error message
"/home/builder/workspace/linux-
hwe-5.11-5.11.0/debian/scripts/misc/arch-has-odm-enabled.sh: line 30:
return: can only `return' from a function or sourced script". That
results in the absent of AAEON from the files "~/workspace/linux-
hwe-5.11-5.11.0/debian/build/build-generic/.config" and
"~/workspace/linux-hwe-5.11-5.11.0/debian/build/build-
lowlatency/.config" as demonstrated below:
grep AAEON
~/workspace/linux-hwe-5.11-5.11.0/debian/build/build-{generic,lowlatency}/.config
# prints nothing
grep AAEON
~/workspace/linux-hwe-5.11-5.11.0/debian/build/build-{generic,lowlatency}/.config.old
# prints:
/home/builder/workspace/linux-hwe-5.11-5.11.0/debian/build/build-generic/.config.old:CONFIG_AAEON_IWMI_WDT=m
/home/builder/workspace/linux-hwe-5.11-5.11.0/debian/build/build-generic/.config.old:CONFIG_GPIO_AAEON=m
/home/builder/workspace/linux-hwe-5.11-5.11.0/debian/build/build-generic/.config.old:CONFIG_LEDS_AAEON=m

/home/builder/workspace/linux-hwe-5.11-5.11.0/debian/build/build-lowlatency/.config.old:CONFIG_AAEON_IWMI_WDT=m
/home/builder/workspace/linux-hwe-5.11-5.11.0/debian/build/build-lowlatency/.config.old:CONFIG_GPIO_AAEON=m
/home/builder/workspace/linux-hwe-5.11-5.11.0/debian/build/build-lowlatency/.config.old:CONFIG_LEDS_AAEON=m
/home/builder/workspace/linux-hwe-5.11-5.11.0/debian/build/build-lowlatency/.config.old:CONFIG_MFD_AAEON=m
/home/builder/workspace/linux-hwe-5.11-5.11.0/debian/build/build-lowlatency/.config.old:CONFIG_SENSORS_AAEON=m
Hence, the AAEON modules are not built, resulting in the five missing
modules and the build failure.
[The fix]
Replace the use of `return' in the script ~/workspace/linux-
hwe-5.11-5.11.0/debian/scripts/misc/arch-has-odm-enabled.sh with
`exit' as shown in the attachment to obtain a successful build as
shown in the quote below:
