Subject: [PATCH 1/2] staging: rtl8723bs: Simplify underutilized 2D array to
 1D array
Message-ID: <4fb8d9783553d15a58e774d7137519d46e58ee3a.1667586648.git.drv@mailo.com>

Precedence: bulk

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.
