Subject: regulator: Include the device name in the microamps_requested_ file
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e0eaedefda8e14ed3f445f382c568c5d69e4223f;p=linux-beck.git

regulator: Include the device name in the microamps_requested_ file

We may have multiple devices requesting a supply with the same name so
include the device name in the generated filename for microamps_requested
to avoid duplicate files.
