| Subject: ARM: OMAP1: ams-delta: Fix broken GPIO ID allocation |
| |
| From: Janusz Krzysztofik <jmkrzyszt@gmail.com> |
| |
| commit 3e2cf62efec52fb49daed437cc486c3cb9a0afa2 upstream. |
| |
| In order to request dynamic allocationn of GPIO IDs, a negative number |
| should be passed as a base GPIO ID via platform data. Unfortuntely, |
| commit 771e53c4d1a1 ("ARM: OMAP1: ams-delta: Drop board specific global |
| GPIO numbers") didn't follow that rule while switching to dynamically |
| allocated GPIO IDs for Amstrad Delta latches, making their IDs |
| overlapping with those already assigned to OMAP GPIO devices. Fix it. |
