[PATCH 3/6 V2] rtlwifi: rtl8192c: Convert driver to use private dm structs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


Convert rtl8192c to use the dm_digtable struct in the common header file
instead of the global variable. Without this change, every instance of
rtl8192ce and rtl8192cu will be using the same global arrays.
