Backport patches that separate spectral scan support from general debugfs support of ath9k/ath10k; this allows to remove the dependency on KERNEL_RELAY from these driver packages even with debugfs enabled and avoids the memory footprint of the relay buffers allocated by ath9k/ath10k even when they aren't used at all. The KERNEL_RELAY dependency is moved to a new config symbol that enables spectral scan support in these drivers. Signed-off-by: Matthias Schiffer <mschiffer@universe-factory.net>master

Subject: [PATCH 2/2] ath10k: move spectral scan support under a separate
|
||||
config symbol
|
||||
|
||||
At the moment, spectral scan support, and with it RELAY, is always enabled
|
||||
with ATH10K_DEBUGFS. Spectral scan support is currently the only user of
|
||||
RELAY in ath10k, and it unconditionally reserves a relay channel.
|
||||
|
||||
Having debugfs support in ath10k is often useful even on very small
|
||||
embedded routers, where we'd rather like to avoid the code size and RAM
|
||||
usage of the relay support. While ath10k-based devices usually have more
|
||||
resources than ath9k-based ones, it makes sense to keep the configuration
|
||||
symmetric to ath9k, so the same base kernel without RELAY can be used for
|
||||
both ath9k and ath10k hardware.
