Subject: [PATCH 25/25] can: mcp251xfd: remove useless code in mcp251xfd_chip_softreset

From: Kaixu Xia <kaixuxia@...cent.com>

It would directly return if the variable err equals to 0 or other errors.
Only when the err equals to -ETIMEDOUT it can reach the 'if (err)'
statement, so the 'if (err)' and last 'return -ETIMEDOUT' statements are
useless. Romove them.

Hello,

I had to manually resend the patch, as it was lost for unknown reasons.

regards,
Marc
