Subject: [PATCH net v2 0/2] net: phy: Fix potential string cut when using PHY_ID_FMT
Date: Wed, 19 Mar 2025 12:54:32 +0200 [thread overview]
Message-ID: <20250319105813.3102076-1-andriy.shevchenko@linux.intel.com> (raw)
The agreement and also PHY_MAX_ADDR limit suggests that the PHY id can't occupy
more than 2 hex digits. In some cases GCC complains about potential string cut.
Avoid that by limiting specifier to print only 2 hex digits (patch 1).
With that, fix the ASIX driver that triggers GCC and use agreed + 3 in the size
of the phy_name (patch 2).
In v2:
- added first patch
- added a conditional to the ASIX driver (Andrew)
