The patch set proposes code cleanup and simplification changes for struct
iqk_matrix_regs_setting member variables. Resultant code is simpler and easier
to maintain.

Member variable "Value" of structure iqk_matrix_regs_setting is
declared to be a 2D array of [3][IQK_Matrix_REG_NUM] grid. However
the primary index of this array is only used for index 0, the other
two elements are never used. Simplify this array to a one dimension
degree. The resultant code is simpler and is easy to maintain.

Member variable bBWIqkResultSaved of struct iqk_matrix_regs_setting is
declared but never used. Remove it.

This field is used to store values (as your above patch shows), but
where is it actually used? Are you sure it is needed at all?

Hi Greg,
For this driver, the values are passed onto setIqkMatrix_8723B() as arguments
and used inside this function. They are needed to be retained in the structure.

Hello Greg,
Upon further review of the structure, I observed that the member "bIQKDone" is
also not used anywhere in the code and it can be removed as well. That cleanup
will lead to replacing this entire structure by a simple one dimensional 'Value"
array.
Please suggest if I should make that change and send in a revision?
