SubjectRe: [PATCH v4 3/5] leds: pwm: check result of led_pwm_set() in led_pwm_add()
Date
Hi Pavel,

here it works.

$ git reset --hard origin/for-next
HEAD is now at 032426ff773f leds: lm3532: make bitfield 'enabled' unsigned
$ curl -s https://lore.kernel.org/patchwork/patch/1213548/mbox/ | git am
Applying: leds: pwm: check result of led_pwm_set() in led_pwm_add()

Strange is that the From: tag in 7bbec6c4b51d is not evaluated at your side.
When I do it, I get:

$ git reset --hard 7a6303677598
HEAD is now at 7a6303677598 leds: leds-is31fl32xx: Replace zero-length array with flexible-array member
$ curl -s https://lore.kernel.org/patchwork/patch/1212782/mbox/ | git am
Applying: leds: leds-pwm: Replace zero-length array with flexible-array member
$ git show
commit e247ae982b5ba113cc9668bec578105645137fb2 (HEAD -> for-next)
Author: Gustavo A. R. Silva <gustavo@embeddedor.com>

leds: leds-pwm: Replace zero-length array with flexible-array member
