Subject: [PATCH] seq_buf: Export seq_buf_printf

References: bsc#1175052 jsc#SLE-13823 bsc#1174969 jsc#SLE-12769
Patch-mainline: v5.8-rc2
Git-commit: 97c02c723bcef11da2f46facdde7c34e72ec8a1f

'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 still not
exported to kernel loadable 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
kernel loadable GPL modules. This symbol will be used in later parts
of this patch-set to simplify content creation for a sysfs attribute.
