Fengguang Wu c4cfb29303 [media] drx-j: drxj_default_aud_data_g can be static 
Fix sparse warning:
	drivers/media/dvb-frontends/drx39xyj/drxj.c:1039:16: sparse: symbol 'drxj_default_aud_data_g' was not declared. Should it be static?

* \fn void mult32(u32 a, u32 b, u32 *h, u32 *l)

* \param a 32 bits multiplicant, typecast from signed to unisgned
* \param b 32 bits multiplier, typecast from signed to unisgned
* \param h pointer to high part 64 bits result, typecast from signed to unisgned
* \param l pointer to low part 64 bits result
*
* For the 2n+n addition a + b:
* if a >= 0, then h += 0 (sign extension = 0)
* but if a < 0, then h += 2^n-1 ==> h -= 1.
*
* Also, if a + b < 2^n, then a + b >= a && a + b >= b
* but if a + b >= 2^n, then R = a + b - 2^n,
* and because a < 2^n && b < 2*n ==> R < a && R < b.
* Therefore, to detect overflow, simply compare the addition result with
* one of the operands; if the result is smaller, overflow has occurred and
* h must be incremented.
*
* Booth multiplication uses additions and subtractions to reduce the number
* of iterations. This is done by taking three subsequent bits abc and calculating
* the following multiplication factor: -2a + b + c. This factor is multiplied
* by the second operand and added to the result. Next, the first operand is
* shifted two bits (hence one of the three bits is reused) and the process
* repeated. The last iteration has only two bits left, but we simply add
* a zero to the end.
*
* Hence: (n=4)
* 1 * a = 0 * 4a + 1 * a
* 2 * a = 1 * 4a - 2 * a
* 3 * a = 1 * 4a - 1 * a
* -1 * a = 0 * 4a - 1 * a
* -5 * a = -1 * 4a - 1 * a
*
* etc.
*
* Note that the function is type size independent. Any unsigned integer type
* can be substituted for booth_t.

Implementation notes.
NTSC/FM AGCs
Four AGCs are used for NTSC:
(1) RF (used to attenuate the input signal in case of to much power)
(2) IF (used to attenuate the input signal in case of to much power)
(3) Video AGC (used to amplify the output signal in case input to low)
(4) SIF AGC (used to amplify the output signal in case input to low)
Video AGC is coupled to RF and IF. SIF AGC is not coupled. It is assumed
that the coupling between Video AGC and the RF and IF AGCs also works in
favor of the SIF AGC.
Three AGCs are used for FM:
(1) RF (used to attenuate the input signal in case of to much power)
(2) IF (used to attenuate the input signal in case of to much power)
(3) SIF AGC (used to amplify the output signal in case input to low)
The SIF AGC is now coupled to the RF/IF AGCs.
The SIF AGC is needed for both SIF ouput and the internal SIF signal to
the AUD block.
RF and IF AGCs DACs are part of AFE, Video and SIF AGC DACs are part of
the ATV block. The AGC control algorithms are all implemented in
microcode.
ATV SETTINGS
(Shadow settings will not be used for now, they will be implemented
later on because of the schedule)
Several HW/SCU "settings" can be used for ATV. The standard selection
will reset most of these settings. To avoid that the end user apllication
has to perform these settings each time the ATV or FM standards is
selected the driver will shadow these settings. This enables the end user
to perform the settings only once after a drx_open(). The driver must
write the shadow settings to HW/SCU incase:
( setstandard FM/ATV) ||
( settings have changed && FM/ATV standard is active)
The shadow settings will be stored in the device specific data container.
A set of flags will be defined to flag changes in shadow settings.
A routine will be implemented to write all changed shadow settings to
HW/SCU.
The "settings" will consist of: AGC settings, filter settings etc.
Disadvantage of use of shadow settings:
Direct changes in HW/SCU registers will not be reflected in the
shadow settings and these changes will be overwritten during a next
update. This can happen during evaluation. This will not be a problem
for normal customer usage.
