Sure, -38 is -ENOSYS which is returned when the wl12xx driver isn't configured.
This isn't an error (it's a user decision, and it shouldn't elicit any
error) and the patch below (also attached) should make it go away on:

Subject: [PATCH] ARM: OMAP: don't print any error when wl12xx isn't
configured
Stop intimidating users with scary wlan error messages in case wl12xx
support wasn't even built.
In addition, when wl12xx_set_platform_data() fails, don't bother
registering wl12xx's fixed regulator device (on the relevant
boards).
While we're at it, extract the wlan init code to a dedicated function to
make (the relevant boards') init code look a bit nicer.
