Bruno Randolf 86415d43ef ath5k: fix I/Q calibration (for real) ... I/Q calibration was completely broken, resulting in a high number of CRC errors on received packets. before i could see around 10% to 20% CRC errors, with this patch they are between 0% and 3%. 1.) the removal of the mask in commit "ath5k: Fix I/Q calibration (f1cf2dbd0f)" resulted in no mask beeing used when writing the I/Q values into the register. additional errors in the calculation of the values (see 2.) resulted too high numbers, exceeding the masks, so wrong values like 0xfffffffe were written. to be safe we should always use the bitmask when writing parts of a register. 2.) using a (s32) cast for q_coff is a wrong conversion to signed, since we convert to a signed value later by substracting 128. this resulted in too low numbers for Q many times, which were limited to -16 by the boundary check later on. 3.) checked everything against the HAL sources and took over comments and minor optimizations from there. 4.) we can't use ENABLE_BITS when we want to write a number (the number can contain zeros). also always write the correction values first and set ENABLE bit last, like the HAL does.
