Missing param value! Expected 'rw=...value...'

[Heiner Kallweit]

Since 60b7cab23e5e ("proc_sysctl: fix oops caused by incorrect command 
parameters.")
I'm getting the following warning: Missing param value! Expected 
'rw=...value...'
AFAIK param rw doesn't require a value. That's what my command line looks like:
Command line: initrd=\intel-ucode.img initrd=\initramfs-linux.img 
root=/dev/sda2 rw
