Subject: bus: ti-sysc: Simplify cleanup upon failures in sysc_probe()
X-Git-Tag: v5.15~5471^2~14^2~9
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a304f483b6b00d42bde41c45ca52c670945348e2;p=platform%2Fkernel%2Flinux-starfive.git

bus: ti-sysc: Simplify cleanup upon failures in sysc_probe()

The clocks are not yet parsed and prepared until after a successful
sysc_get_clocks(), so there is no need to unprepare the clocks upon
any failure of any of the prior functions in sysc_probe(). The current
code path would have been a no-op because of the clock validity checks
within sysc_unprepare(), but let's just simplify the cleanup path by
returning the error directly.

While at this, also fix the cleanup path for a sysc_init_resets()
failure which is executed after the clocks are prepared.
