[PATCH net 1/2] can: dev: keep the max bitrate error at 5%

[Marc Kleine-Budde <mkl@pengutronix.de>]

From: Haibo Chen <haibo.chen@nxp.com>

Commit b360a13d44db ("can: dev: print bitrate error with two decimal
digits") changed calculation of the bit rate error from on-tenth of a
percent to on-hundredth of a percent, but forgot to adjust the scale of the
CAN_CALC_MAX_ERROR constant.

Keeping the existing logic unchanged: Only when the bitrate error exceeds
5% should an error be returned. Otherwise, simply output a warning log.

Fixes: b360a13d44db ("can: dev: print bitrate error with two decimal digits")
