scripts: decode_stacktrace: fix ARM architecture decoding
Fix the stack decoder for the ARM architecture.
An ARM stack is designed as :
[ 81.547704] [<c023eb04>] (bucket_find_contain) from [<c023ec88>] (check_sync+0x40/0x4f8)
[ 81.559668] [<c023ec88>] (check_sync) from [<c023f8c4>] (debug_dma_sync_sg_for_cpu+0x128/0x194)
[ 81.571583] [<c023f8c4>] (debug_dma_sync_sg_for_cpu) from [<c0327dec>] (__videobuf_s
The current script doesn't expect the symbols to be bound by
parenthesis, and triggers the following errors :
awk: cmd. line:1: error: Unmatched ( or \(: / (check_sync$/
[ 81.547704] (bucket_find_contain) from (check_sync+0x40/0x4f8)
Fix it by chopping starting and ending parenthesis from the each symbol
name.
As a side note, this probably comes from the function
dump_backtrace_entry(), which is implemented differently for each
architecture. That makes a single decoding script a bit a challenge.
