[ Upstream commit 375ba74841 ]
Since the timer uses jiffies as its unit rather than ms, the timeout value
must be converted from ms to jiffies when configuring the timer. Otherwise,
the intended 8s timeout is incorrectly set to approximately 33s.
To improve readability, embed msecs_to_jiffies() directly in the macro
definitions and drop the _MS suffix from macros that now yield jiffies
values: MEMDUMP_TIMEOUT, FW_DOWNLOAD_TIMEOUT, IBS_DISABLE_SSR_TIMEOUT,
CMD_TRANS_TIMEOUT, and IBS_BTSOC_TX_IDLE_TIMEOUT.
IBS_WAKE_RETRANS_TIMEOUT_MS and IBS_HOST_TX_IDLE_TIMEOUT_MS are
intentionally left unchanged. Their values are stored in the struct fields
wake_retrans and tx_idle_delay, which hold ms values at runtime and can be
modified via debugfs. The msecs_to_jiffies() conversion happens at each
call site against the field value, so it cannot be embedded in the macro.
Wake timer depends on commit c347ca17d6
