Hello,
while working on an defconfig (arm/mx27) I noticed that just updating
it[1] results in removing CONFIG_EEPROM_AT24=y. The reason is that
since commit
v2.6.36-5965-g5f2365d (misc devices: do not enable by default)
MISC_DEVICES isn't enabled anymore by default. So all defconfigs that
have CONFIG_SOME_SYMBOL=y (or =m) (with SOME_SYMBOL depending on
MISC_DEVICES) but not CONFIG_MISC_DEVICES=y suffer from the same
problem.
As a defconfig that was reduced before 5f2365d obviously didn't have
CONFIG_MISC_DEVICES=y many defconfigs have that problem.
I did the following to (hopefully) find all affected defconfigs:
$ git describe
v2.6.38-rc7
$ git ls-files drivers/misc | grep Kconfig | xargs grep -h ^config | sed 's/config \(.*\)/CONFIG_\1=/' > miscsymbols
$ git ls-files *defconfig | xargs grep -L CONFIG_MISC_DEVICES= | xargs grep -F -f miscsymbols

(For those wondering about the commands above: A line
arch/$arch/configs/xyz_defconfig:CONFIG_SOME_DEVICE=y
means here, that running
make ARCH=$arch xyz_defconfig
results in a config without SOME_DEVICE.
I don't know if that bothers you, but if it does, you should add
CONFIG_MISC_DEVICES=y
to your defconfig.
Just to let you know ...
Best regards
Uwe
