We are planning to use struct and le32_get_bits() directly, so don't introduce
this old style anymore. An example is
struct rtw8703b_phy_stat {
__le32 w0;
__le32 w1;
...
};
#define RTW8703B_PHY_STAT_W0_AGC_GAIN_A GENMASK(6, 0)
val_s8 = le32_get_bits(stat->w0, RTW8703B_PHY_STAT_W0_AGC_GAIN_A);

Is this comment for 0x0e90? move to rear of the line?
