The patch titled Subject: leds: add LED driver for lm3556 chip has been removed from the -mm tree. Its filename was leds-add-led-driver-for-lm3556-chip.patch This patch was dropped because it was withdrawn The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ From: Geon Si Jeong <gshark.jeong@xxxxxxxxx> Subject: leds: add LED driver for lm3556 chip A simple driver for the Texas Instruments LM3556 chip. The LM3556 is a 4 MHz fixed-frequency synchronous boost converter plus 1.5A constant current driver for a high-current white LED.
