[PATCH v2 0/1] leds: lgm: Address review concerns

[Rahul Tanwar]

Address below review concerns from Pavel:
1. Remove LEDS_BLINK Kconfig symbol.
2. Provide useful Kconfig help text for the driver.

This patch is based on "for-next" branch of kernel from below git tree:
git git://git.kernel.org/pub/scm/linux/kernel/git/pavel/linux-leds.git for-next

v2:
- Fix few code quality related review concerns (Randy Dunlap).
- Further improve Kconfig help text (Pavel).
- Switch back to original copyright (pavel).

v1:
- Initial version.
