Subject: serial: doc: .break_ctl() may sleep
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=101ca9ccdd30c46afc5c9a30e7acdcbeaa330fa1;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

serial: doc: .break_ctl() may sleep

break_ctl() is not called from any sort of atomic context, so there is no
problem with it sleeping.
