X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bd05086bbe3f241cd552068f9ceba9e19c6ce427;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

driver core: Convert to kasprintf() for early dev_name().

This is just a simple refactoring patch on top of the early dev_name()
support, converting from kstrdup() to kasprintf() as suggested by Kay.
