But doesn't that represent some bogus manipulation of the irq flags? cf.However, if local_irq_save() is called when irq is disabled. The SR_IE bit of
flag returned is clear. If some code between local_irq_save() and
local_irq_restore() reenables irq, causing the SR_IE bit of CSR_STATUS
back to 1, then local_irq_restore() can not restore irq status back to disabled.

Enables checks for potentially unsafe enabling or disabling of
interrupts, such as calling raw_local_irq_restore() when interrupts
are enabled.
in particular, raw_check_bogus_irq_restore() in raw_local_irq_restore().
This got lost but this is still correct and needed.You mean because of the mentioned rtl8723e example? are there other such
instances? IOW, why do you say that the changes in question are needed?
