Subject: [PATCH] acpi, nfit: remove redundant __func__ in dev_dbg
Dynamic debug can be instructed to add the function name to the debug
output using the +f switch, so there is no need for the nfit module to
do it again. If a user decides to add the +f switch for nfit's dynamic
debug this results in double prints of the function name like the
following:
[ 2391.935383] acpi_nfit_ctl: nfit ACPI0012:00: acpi_nfit_ctl:nmem8 cmd: 10: func: 1 input length: 0
Thus remove the stray __func__ printing.
