Subject: iwlwifi: mvm: remove the default calibration values for 7000
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=58fa2aad295579a0fcab699eb76bff79eb8df3a8;p=linux-beck.git

iwlwifi: mvm: remove the default calibration values for 7000

The fw is now able to run TX_IQ_SKEW and RX_IQ_SKEW by
itself. No need for default values any more.
