Subject: can: flexcan: flexcan_chip_freeze(): fix chip freeze for missing bitrate
|
||||
|
||||
From: Angelo Dureghello <angelo@kernel-space.org>
|
||||
|
||||
commit 47c5e474bc1e1061fb037d13b5000b38967eb070 upstream.
|
||||
|
||||
For cases when flexcan is built-in, bitrate is still not set at
|
||||
registering. So flexcan_chip_freeze() generates:
|
||||
|
||||
[ 1.860000] *** ZERO DIVIDE *** FORMAT=4
|
||||
[ 1.860000] Current process id is 1
|
||||
[ 1.860000] BAD KERNEL TRAP: 00000000
|
||||
[ 1.860000] PC: [<402e70c8>] flexcan_chip_freeze+0x1a/0xa8
|
||||
|
||||
To allow chip freeze, using an hardcoded timeout when bitrate is still
|
||||
not set.
|
||||
|
||||
Fixes: ec15e27cc890 ("can: flexcan: enable RX FIFO after FRZ/HALT valid")
