Subject: [PATCH AUTOSEL 6.10 037/197] bnxt_en: Extend maximum length of version string by 1 byte

From: Simon Horman <horms@...nel.org>

[ Upstream commit ffff7ee843c351ce71d6e0d52f0f20bea35e18c9 ]

This corrects an out-by-one error in the maximum length of the package
version string. The size argument of snprintf includes space for the
trailing '\0' byte, so there is no need to allow extra space for it by
reducing the value of the size argument by 1.

Found by inspection.
Compile tested only.
