Subject: hwmon: (core) remove redundant cast
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3b443def46cc730c0ba590c5692d085b80a8659c;p=linux.git

hwmon: (core) remove redundant cast

struct attribute::name which this local variable name is eventually
assigned to is "const char*", and so is the template parameter. We might
as well preserve the constness all the way through.
