Subject: mfd: ucb1x00-assabet: Use DEVICE_ATTR_RO macro
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=47ed390bac52c5814c03253d15a6ffe85ef69ba5;p=linux.git

mfd: ucb1x00-assabet: Use DEVICE_ATTR_RO macro

Use DEVICE_ATTR_RO macro helper instead of plain DEVICE_ATTR, which makes
the code a bit shorter and easier to read.
