[PATCH] platform/x86: toshiba_acpi: Fix missing error code in toshiba_acpi_setup_keyboard()

[Jiapeng Chong]

The error code is missing in this code scenario, add the error code
'-EINVAL' to the return value 'error'.

Eliminate the follow smatch warning:

drivers/platform/x86/toshiba_acpi.c:2834 toshiba_acpi_setup_keyboard()
warn: missing error code 'error'.

Thank you for your patch, I've applied this patch to my review-hans 
branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans

Note it will show up in my review-hans branch once I've pushed my
local branch there, which might take a while.

Once I've run some tests on this branch the patches there will be
added to the platform-drivers-x86/for-next branch and eventually
will be included in the pdx86 pull-request to Linus for the next
merge-window.

Regards,

Hans
