https://git.0xinfinity.dev/distro/kernel.git/atom?h=linux-2.6.28.y2008-08-01T19:50:15Ztry harder to load tty ldisc driver2008-08-01T19:50:15ZEugeniy Meshcheryakov2008-07-31T09:03:19Zurn:sha1:3ab36ab68531ad90648fdeedcaf437f121572ede
Currently function tty_ldisc_get() tries to load an ldisc driver module
only when tty_ldisc_try_get() returns -EAGAIN. This happens only if
module is being unloaded. If ldisc module is not loaded
tty_ldisc_try_get() returns -EINVAL and this case is not handled in
tty_ldisc_get(), so request_module() is not called.
Attached patch fixes this by calling request_module() if
tty_ldisc_try_get() returned any error code.
I discovered this when my UMTS modem stopped working with 2.6.27-rc1
because module ppp_async was not loaded.
