The config symbol was only there to avoid the compile error due to the missing fallback for print_hex_dump_debug in the CONFIG_DYNAMIC_DEBUG=n case. That was fixed with commit cdf17449af1d "hexdump: do not print debug dumps for !CONFIG_DEBUG", so the config symbol can just be dropped. Cc: Joe Perches Signed-off-by: Dan Williams --- Changes in v2: * Thanks to Joe for pointing out the misunderstanding about print_hex_dump_debug() compilation being broken in the CONFIG_DYNAMIC_DEBUG=n case. Since commit cdf17449af1d we can rely on print_hex_dump_debug() to do the right thing by default. drivers/acpi/nfit/Kconfig | 12 ------------ drivers/acpi/nfit/core.c | 21 ++++++++------------- 2 files changed, 8 insertions(+), 25 deletions(-) diff --git a/drivers/acpi/nfit/Kconfig b/drivers/acpi/nfit/Kconfig index dd0d53c52552..6d3351452ea2 100644 --- a/drivers/acpi/nfit/Kconfig +++ b/drivers/acpi/nfit/Kconfig @@ -12,15 +12,3 @@ config ACPI_NFIT To compile this driver as a module, choose M here: the module will be called nfit. - -config ACPI_NFIT_DEBUG - bool "NFIT DSM debug" - depends on ACPI_NFIT - depends on DYNAMIC_DEBUG - default n - help - Enabling this option causes the nfit driver to dump the - input and output buffers of _DSM operations on the ACPI0012 - device and its children.
