Subject: [RESEND PATCH v7 2/5] seq_buf: Export seq_buf_printf() to external modules

'seq_buf' provides a very useful abstraction for writing to a string
buffer without needing to worry about it over-flowing. However even
though the API has been stable for couple of years now its stills not
exported to external modules limiting its usage.

Hence this patch proposes update to 'seq_buf.c' to mark
seq_buf_printf() which is part of the seq_buf API to be exported to
external GPL modules. This symbol will be used in later parts of this
patchset to simplify content creation for a sysfs attribute.
