Subject: sfc: avoid division by zero
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=c7b256f998f6d00d4548090aa16fb34e005828c1;p=deliverable%2Flinux.git

sfc: avoid division by zero

The division is already being done properly in efx_ef10_get_timer_config
which returns zero-on-success, unlike the old efx_ef10_get_sysclk_freq.

Fixes: d95e329a55ba ("sfc: get timer configuration from adapter")
