| Subject: net: emaclite: Fix missing pointer increment in aligned_read() |
| |
| From: Alok Tiwari <alok.a.tiwari@oracle.com> |
| |
| [ Upstream commit 7727ec1523d7973defa1dff8f9c0aad288d04008 ] |
| |
| Add missing post-increment operators for byte pointers in the |
| loop that copies remaining bytes in xemaclite_aligned_read(). |
| Without the increment, the same byte was written repeatedly |
| to the destination. |
| This update aligns with xemaclite_aligned_write() |
| |
| Fixes: bb81b2ddfa19 ("net: add Xilinx emac lite device driver") |
