The LED1202 is a 12-channel low quiescent current LED driver with:
* Supply range from 2.6 V to 5 V
* 20 mA current capability per channel
* 1.8 V compatible I2C control interface
* 8-bit analog dimming individual control
* 12-bit local PWM resolution
* 8 programmable patterns
If the led node is present in the controller then the channel is
set to active.

+description: |
+ The LED1202 is a 12-channel low quiescent current LED controller
+ programmable via I2C; The output current can be adjusted separately
+ for each channel by 8-bit analog and 12-bit digital dimming control.

Without additional context, I don't think this is a reasonable request. If you're a maintainer of an affected subsystem and the set is at v10, you should expect to receive (and discard) the submission 10 times. I certainly don't start stripping out maintainers once they've provided their A-b or R-b, do you do that? -- Lee Jones [李琼斯]

I received the same patch - v10 - like 5 or 6 times. I replied to the last one, apparently all others were sent only to me. > > I certainly don't start stripping out maintainers once they've provided > their A-b or R-b, do you do that?

This is the command I used: $ git send-email --to-cmd='./scripts/get_maintainer.pl --norolestats v11/v11-000*' v11/v11-000* I received the submitting only once and I do not know why it sent you 5 times.
