Subject: net: stmmac: xgmac: fix a typo of register name in DPP safety
handling
Patch-mainline: v6.8-rc4
Git-commit: 1ce2654d87e2fb91fea83b288bd9b2641045e42a
References: bsc#1222445 CVE-2024-26684
DDPP is copied from Synopsys Data book:
DDPP: Disable Data path Parity Protection.
When it is 0x0, Data path Parity Protection is enabled.
When it is 0x1, Data path Parity Protection is disabled.
The macro name should be XGMAC_DPP_DISABLE.
Fixes: 46eba193d04f ("net: stmmac: xgmac: fix handling of DPP safety error for DMA channels")
