Subject: [PATCH] orinoco: simplify locking, fix error handling in PCMCIA resume
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6cbaa330f1022abfc7419aaa11ee1a9291f0beb0;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] orinoco: simplify locking, fix error handling in PCMCIA resume

Don't use flags in the spinlocks - the PCMCIA resume functions may not
be called under lock.  Don't ignore any errors.
