Subject: [PATCH] igc: Fix the typo in the PTM Control macro
References: bsc#1012628
Patch-mainline: 6.4.13
Git-commit: de43975721b97283d5f17eea4228faddf08f2681
[ Upstream commit de43975721b97283d5f17eea4228faddf08f2681 ]
The IGC_PTM_CTRL_SHRT_CYC defines the time between two consecutive PTM
requests. The bit resolution of this field is six bits. That bit five was
missing in the mask. This patch comes to correct the typo in the
IGC_PTM_CTRL_SHRT_CYC macro.
Fixes: a90ec8483732 ("igc: Add support for PTP getcrosststamp()")
