| Subject: brcmfmac: increase buffer for obtaining firmware capabilities |
| |
| From: Arend van Spriel <arend.vanspriel@broadcom.com> |
| |
| [ Upstream commit 59c2a30d36c8ae430d26a902c4c9665ea33ccee5 ] |
| |
| When obtaining the firmware capability a buffer is provided of 512 |
| bytes. However, if all features in firmware are supported the buffer |
| needs to be 565 bytes as otherwise truncated information is retrieved |
| from firmware. Increasing the buffer to 768 bytes on stack. |
