Subject: [PATCH] firmware: bcm47xx_nvram: look for NVRAM with for instead of
while
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This loop requires variable initialization, stop condition and post
iteration increment. It's pretty much a for loop definition.
