An earlier bugfix introduced a dependency on CONFIG_NET_SCH_TAPRIO, but this missed the case of NET_SCH_TAPRIO=m and NET_DSA_SJA1105=y, which still causes a link error: drivers/net/dsa/sja1105/sja1105_tas.o: In function `sja1105_setup_tc_taprio': sja1105_tas.c:(.text+0x5c): undefined reference to `taprio_offload_free' sja1105_tas.c:(.text+0x3b4): undefined reference to `taprio_offload_get' drivers/net/dsa/sja1105/sja1105_tas.o: In function `sja1105_tas_teardown': sja1105_tas.c:(.text+0x6ec): undefined reference to `taprio_offload_free' Change the dependency to only allow selecting the TAS code when it can link against the taprio code.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
