mfw/ti1_key.c: properly initialize notified_keys array The code in this ti1_key.c layer needs to call kpd_subscribe() and kpd_define_key_notification() functions in order to register with the KPD driver. The original code passed KPD_NB_PHYSICAL_KEYS in nb_notified_keys - this constant is defined to 24 in kpd_cfg.h on all platforms of interest to us - but it only filled the first 23 slots in the notified_keys array, resulting in stack garbage being passed to KPD API functions. The fix consists of initializing the last missed array slot to KPD_KEY_RECORD, the key ID for the right side button on the D-Sample handset. On our current hw targets this "Record" button exists as the EXTRA button on our Luna keypad board and as the camera button on the Pirelli DP-L10. There is no support whatsoever for this button in current BMI+MFW, we have no plans of doing anything with Pirelli's camera button even if we do get our UI fw running on that phone, and the Mother's dream of building our own FreeCalypso handset with the same button arrangement as D-Sample (including the right side button) is currently very nebulous - but let us nonetheless handle the full set of buttons on the KPD to MFW interface, and let upper layers weed out unsupported buttons.

  PURPOSE : Decoding of the non-standard type CSN1 S0 element.
            The encoding rule for this type is very similar to the 
            CSN.1 type. Except for the presence flag which is 0 in 
            this case. 
            The encoded IE consists of one bit for presence flag and 
            a value part. Only if the flag bit is equal 0 the value 
            part will follow it.

  PURPOSE : Encoding of the non-standard type CSN1 S0 element.
            The encoding rule for this type is very similar to CSN.1
            type. Except for the presence flag which is 0 in this
            case. The encoded bit pattern consists of a 0 bit as 
            valid flag and a value part. If the element is present
            (the v_xxx component is TRUE in the decoded message)
            a 0 bit will be coded followed by the encoded value part.
            Otherwise a 1 bit will be encoded.
            Possible array types are given by melem[e_ref].repType:
            0) ' ' =>  {0| IE}        (no array)
            1) 'i' =>  {0 IE} ** 1    (many repeations up to a 1 bit)
            2) 'v' =>  {0|1 IE}* val  (val is another IE)
            3) 'c' =>  {0|1 IE}* 3    (3 is  an example)
