-Subject: [PATCH] firmware: bcm47xx_nvram: inline code checking NVRAM size
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Separated function was not improving code quality much (or at all).
-Moreover it expected possible flash end address as argument and it was
-returning NVRAM size.
-
-The new code always operates on offsets which means less logic and less
-calculations.
