This is an update to the syntactic results that I sent, back in July.
With kernel 3.12 nearing completion, I would like to point to new sections
in Kconfig files with potential problems:
drivers/media/common/siano/Kconfig:21-26
> config SMS_SIANO_DEBUGFS
> bool "Enable debugfs for smsdvb"
> depends on SMS_SIANO_MDTV
> depends on DEBUG_FS
> depends on SMS_USB_DRV
> depends on CONFIG_SMS_USB_DRV = CONFIG_SMS_SDIO_DRV
The last line adds the dependency CONFIG_SMS_USB_DRV = CONFIG_SMS_SDIO_DRV.
This expression does not look sound as those two symbols are not declared
anywhere. So, the two strings CONFIG_SMS_USB_DRV and CONFIG_SMS_SDIO_DRV
are compared, yielding always 'n'. As a result, SMS_SIANO_DEBUGFS will never
be enabled.
Probably, it was meant to say something like
> depends on SMS_USB_DRV = SMS_SDIO_DRV
Two other config sections that probably behave differently than expected:
drivers/staging/rtl8188eu/Kconfig: 13-15
> config 88EU_AP_MODE
> bool "Realtek RTL8188EU AP mode"
> default Y
drivers/staging/rtl8188eu/Kconfig: 21-23
> config 88EU_P2P
> bool "Realtek RTL8188EU Peer-to-peer mode"
> default Y
The capital Y is different from the lowercase y. While y is an actually
hard coded constant symbol, Y is undeclared and evaluates to n.
The default values are probably only for convenience, so 88EU_AP_MODE and
88EU_P2P are activated together with 8188EU. They still can be turned off.
Anyway, it should probably say "default y" in both cases.
Here the updated full two lists from July:
