[PATCH 6/7] pinctrl: k210: Fix loop in k210_pc_get_drive()

[Niklas Cassel]

From: Niklas Cassel <niklas.cassel at wdc.com>

The loop exited too early so the k210_pc_drive_strength[0] array element
was never used.

Original Linux patch by Dan Carpenter:

Fixes: 7224d5ccf8e1 ("pinctrl: Add support for Kendryte K210 FPIOA")
